students in UTM before they are qualified to graduate from the university.
Industrial training is a prerequisite for all students taking Bachelors of
Mechanical Precision Engineering and all engineering students must complete
the training before the last semester. The industrial training is the platform for
the students to have the experiences on the working field by applying the
knowledge that the students gain from the university. Choosing the right path
to do the industrial training is the key for receiving valuable experiences and
knowledge on the steps for applying jobs after the students graduate. The
industrial training is also a platform for students to choose the company that
suits the student’s interest of working.
The starting date for the industrial training is 16th
June 2014 and the
completion date is on 11th
July 2014. Keio University is a private,
comprehensive higher education institution located on six campuses spread
across the Greater Tokyo area. It offers an environment of academic and
research excellence in a wide range of fields, and includes a university hospital.
Industrial training is a hand on experience after learning the concept or theory
in class. The training will motivate the students to increase their knowledge
not only in theory parts but also on the practical parts. The training also gives a
true picture about future study and a part kind of industry life and students
must face the pressure and workload that they receive during the training
period. In advance, students will also have the willing to perform better for the
remaining study semester to receive a good job with excellent salary after
graduate. The industrial training is one of the best methods of study after
learning the concepts and theory in university. The training also provides the
first valuable introduction to the global view of studies outside from Malaysia
especially Japan, well known with their future engineering advance to boost
nation development better.

2.0 INTRODUCTION
Industrial Training (IT) is a student placement in an industry or outside organization (locally
or abroad) for a period of eight (8) weeks. The IT is designed for a student to practice
knowledge gained at university in the workplace as part of the fulfilment of the Bachelor
Degree Award.
a) It is compulsory for every MJIIT undergraduate student to undergo Industrial training for
a specified period of time under the course code of SMJG 3206.
b) The training serves as an exposure to the real work environment so that the student can
relate theories learned in class and apply them in the workplace to prepare them for their
future career as a professional engineer.
c) The students are placed in industries related to their areas of studies for a period of eight
(8) weeks. The word ‘industries’ here include the whole of engineering activities such as
consultancy, research and development, manufacturing etc. and the industry can be local or
overseas. The training should provide workplace experience that requires the student to
practically do the task and be able to apply their knowledge in the industrial setting. Every
student is required to submit a written report based on their industrial training experience.

3.0 UNIVERSITY INFORMATION
3.1 UNIVERSITY OVERVIEW
Keio University is a private, comprehensive higher education institution located on six
campuses spread across the Greater Tokyo area. It offers an environment of academic and
research excellence in a wide range of fields, and includes a university hospital. Founded in
1858, it is Japan’s first modern institution of higher learning and over the last century and a
half it has established itself as a leader in Japan through its continued commitment to
education, research and medicine.
Keio has its origins in the school of Western learning established by Yukichi Fukuzawa, a
school which soon evolved into a major center of learning. As a highly respected educator
and intellectual, Fukuzawa was one of the pioneers of modern Japan. He aspired for Keio to
become a model and leader of society, stressing the importance of learning that is based on
jitsugaku, or “science”. In today’s changing world, Keio upholds its founder’s spirit of science
as it continues to fulfill his aspiration.
3.1.1 CAMPUS INFORMATION
Keio University is a comprehensive academic enterprise with six major campuses in Japan,
along with a number of affiliated academic institutions on or near these campuses. In
addition, Keio University also operates a high school in New York.
Since its inception, Keio has continued to pursue Yukichi Fukuzawa's spirit of jitsugaku,
which holds that one should not just acquire information from book learning, but should
learn from real-life experiences in order to apply viable solutions to actual problems. Keio
continues to pursue jitsugaku today, fostering forward-looking thinkers at its six major
campuses.
KEIO UNIVERSITY

Figure 1: Yagami Campus
Figure 1 shows Yagami campus of KEIO’s situated on a hill adjacent to the Hiyoshi Campus,
the Yagami Campus was built in 1972 as the home of the Faculty of Science and Technology
and the Graduate School of Science and Technology. This campus houses the latest in high-
tech facilities for the education of tomorrow's scientists and engineers.
3.1.2 KEIO’S HISTORY
Keio University traces its beginnings to the original Keio Gijuku, an institution of Western
learning unlike any other in Japan in its time. Founder Yukichi Fukuzawa (1835-1901) was a
man of uncommon courage, vision, and wisdom who defied the established powers of the
time and pursued knowledge above all else, endeavoring to understand the society and
morals of 19th century civilization in Europe and North America. His beliefs were very
progressive in a Japan that was just beginning to awake from centuries of isolation. His
convictions and deeds made an indelible mark on the country that would, barely more than
a century later, become the second-largest economic power in the free world.
Since its founding in 1858, the history of Keio University parallels the history of Japan's
modern era. The vision and clarity of founder Yukichi Fukuzawa's original teachings have
held up well for nearly a century and a half of serious academic inquiry in the service of
Japan's development and modernization. Fukuzawa believed that Japan's only choice for
catching up with Western technology and social organization was to "always strive for
progress and enlightenment, and provide the academic and moral education needed to
create a generation of wise and capable leaders." To this end, Keio University has continued
to provide intellectual leadership that addresses the issues facing Japanese society in its
quest for development, transformation, and modernization. As we face the challenges of
the post-industrial era of the 21st century, Keio continues to uphold the pioneer spirit of its
founder in his pursuit of peace, prosperity, and progress.
KEIO UNIVERSITY

3.2 UNIVERSITY MISSION
Keio University is not merely a place for academic pursuit. Its mission is to be a constant
source of honourable character and a paragon of intellect and morals for the entire nation
and for each member to apply this spirit to elucidate the essence of family, society, and
nation. They will not only articulate this essence in words, but also demonstrate it in their
actions, and by so doing make Keio a leader of society.
4.0 GENERAL STATEMENT OF THE TRAINING
4.1 INTRODUCTION
On 16th June 2014, I came to FACULTY OF SCIENCE AND TECHNOLOGY, YAGAMI campus,

4.3 SCOPE OF WORK, TRAINING AND PROJECT CARRIED OUT
Below are my activities during the Industrial Training from 16th June until 11th July 2014 at
KEIO’s University:
4.3.1 MAIN TASK/PROJECT
Senpai Mr. Ishizuka (PHD student)
Project/Thesis about “Tactile Display for Stiffness Distribution with MR Fluid”
 Focus study:
 ARDUINO DUE board with ARDUINO programming language to
send command
 Linear Actuator comes with 5-phase and hardware (driver)
 Objective :
 The current mechanism manually, thus want to make it
automatically functioning according to the command receive.
4.3.2 MAIN IDEA
1) How did I get the intention about MR fluid?
I have heard about MR suspension systems before, MR is in fact a carrier fluid, usually oil,
which is filled with micrometer-sized magnetic particles. When subjected to a magnetic field,
the magnetic particles inside increase the fluid's viscosity, rendering it viscoelastic solid.
Usually, a MR suspension system is made of four magnetorheological struts or shock
absorbers, a sensor set and an electronic control unit (ECU). These technology were used by
well-known German manufacturer Audi, with its introduction car model TT & R8.
Figure 4: Supercar of Audi R8 Sports Edition
For instance, in Audi TT's case, the driver can choose between "Normal" and "Sport"
programs by flipping a switch and the system reacts accordingly, providing different damper
response.

2) What is ARDUINO DUE board and ARDUINO programming language?
The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3
CPU (datasheet). It is the first Arduino board based on a 32-bit ARM core microcontroller. It
has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs,
4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC
(digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an
erase button. Unlike other Arduino boards, the Arduino Due board runs at 3.3V. The
maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to
an I/O pin could damage the board.
Figure 5: ARDUINO DUE board
The Arduino Due can be programmed with the Arduino software. From figure 5 shows either
of the USB ports can be used for programming the board, though it is recommended to use
the Programming port due to the way the erasing of the chip is handled:
Programming port: To use this port, select "Arduino Due (Programming Port)" as your board
in the Arduino IDE. Connect the Due's programming port (the one closest to the DC power
jack) to your computer. The programming port uses the 16U2 as a USB-to-serial chip
connected to the first UART of the SAM3X (RX0 and TX0). The 16U2 has two pins connected
to the Reset and Erase pins of the SAM3X. Opening and closing the Programming port
connected at 1200bps triggers a “hard erase” procedure of the SAM3X chip, activating the
Erase and Reset pins on the SAM3X before communicating with the UART. This is the
recommended port for programming the Due. It is more reliable than the "soft erase" that
occurs on the Native port, and it should work even if the main MCU has crashed.
Native port: To use this port, select "Arduino Due (Native USB Port)" as your board in the
Arduino IDE. The Native USB port is connected directly to the SAM3X. Connect the Due's
Native USB port (the one closest to the reset button) to your computer. Opening and closing
the Native port at 1200bps triggers a 'soft erase' procedure: the flash memory is erased and
the board is restarted with the bootloader. If the MCU crashed for some reason it is likely
that the soft erase procedure won't work as this procedure happens entirely in software on
the SAM3X. Opening and closing the native port at a different baudrate will not reset the
SAM3X.

High Torque Stepping Motors
The PK Series 0.72°stepping motor offers high torque, our lowest vibration and noise. This
motor is wound in the bipolar New Pentagon configuration and therefore, require a New
Pentagon bipolar type driver. The New Pentagon configuration ensures that maximum
torque is being generated by the motor on every step. The New Pentagon configuration also
provides extremely smooth motion as well as maintaining torque and step accuracy
regardless of the step resolution.

***Please Refer Appendix B for full article about Operating Manual
Improved Torque
This motor combines high torque
and a compact size. Three frame
sizes, 0.79 in. (20mm), 1.10 in.
(28mm) and 1.65 in. (42mm), are
available. The high torque motor
generates approximately 1.3 to 1.5
times the torque achieved by the
standard type.

4.3.3 SPECIFIC THEORY
First and foremost, to use ARDUINO DUE board we need to use the ARDUINO programming
language to send command and any related function. Basically this software and the
language is quite similar to the programming C/C++.
Figure 8: ARDUINO development environment software & sample code
I have my self-study about this programming language about 1 week and at the same time I
have to know about ARDUINO DUE board each function. My senpai have been requested
me to study how signal been received & send within computer and ARDUINO board and at
the same time understand all the mechanism of each component of ARDUINO DUE board
before proceed.

Oscilloscope
An oscilloscope, previously called an oscillograph, and informally known as a scope, CRO (for
cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a
type of electronic test instrument that allows observation of constantly varying signal
voltages, usually as a two-dimensional plot of one or more signals as a function of time.
Non-electrical signals (such as sound or vibration) can be converted to voltages and
displayed.
Figure 9: Oscilloscope with display
Oscilloscopes are used to observe the change of an electrical signal over time, such that
voltage and time describe a shape which is continuously graphed against a calibrated scale.
The observed waveform can be analyzed for such properties as amplitude, frequency, rise
time, time interval, distortion and others. Modern digital instruments may calculate and
display these properties directly.
Originally, calculation of these values required manually measuring the waveform against
the scales built into the screen of the instrument.
The oscilloscope can be adjusted so that repetitive signals can be observed as a continuous
shape on the screen. A storage oscilloscope allows single events to be captured by the
instrument and displayed for a relatively long time, allowing human observation of events
too fast to be directly perceptible.
Oscilloscopes are useful for looking at very fast changes in voltage over time, things that we
could not measure with a multimeter. Usually when you make a measurement with an
oscilloscope, you will see a line that stretches from one side of the screen to the other; this
line is actually a graph of voltage vs time (fig 2), where voltage is measured along the y axis
and time along the x.
Oscilloscopes come in two varieties: analog and digital(I'll be using a digital scope in this
tutorial). The controls on both types are basically the same; be aware that the digital scopes
may hide some of there controls in a menu on the LCD display instead of using knob or
button.

Pulse-Width Modulation (PWM)
 Digital square wave, where frequency is constant, but fraction time the signal
is on ( duty cycle )
 By changing the pulse width, we change the average voltage seen by circuit
( pulse width modulation technique )
For example 10V ~ If duty cycle is 10%, only effective average of 1 volt
Have 3 main characteristics:
 Amplitude – amount of signal changes between on & off states
 Frequency – number of times the signal repeat in given time frame
 Duty cycle – proportion of on time to off time usually expressed as percentage.
The simplest waveform to get an Arduino to produce is a square wave. The square wave (as
the name suggests) simply cycles between the HIGH and LOW logical levels.
Figure 10: Square Wave produced with oscilloscope
Apart from the frequency of the wave, there are a couple of other main characteristic that
we might want to modify: the amplitude (a measure of how much higher the HIGH level is,
compared to the LOW), and the symmetry of the wave – the so-called duty cycle. We’ll
leave the amplitude aside until next time – as that’ll require us to do a little more work; but
let’s look at the duty cycle of the wave.
The duty cycle is simply a measure of how much of the time our wave is at the HIGH level –
compared with the total time of the cycle. So far all of our square waves have been
symmetrical: with an equal amount of time spent in both states. This is known as a 50% duty
cycle.

Connection & Operation
The 5-Phase stepping motor need a driver to be successfully connected within controller
(ARDUINO DUE).
Figure 11: Motor driver
Figure 12: Wiring diagram between controller, driver and motor
***Please Refer Appendix D for full view about overall Connection & Operation
◇ Input Signal Connection
Signals can be connected directly when 5 VDC
is supplied. If the signals are used at a
voltageexceeding 5 VDC, be sure to provide an
external resistor to prevent the current
exceeding 20 mAfrom flowing. Internal
components will be damaged if a voltage
exceeding 5 VDC is supplieddirectly without
using an external resistor.Example: If the
voltage is 24 VDC, connect a resistor (R1) of 1.5
to 2.2 kΩ and 0.5 W or more.
◇ Output Signal Connection
Use output signals at 24 VDC or less and 10 mA
or less.If these specifications are exceeded, the
internal components may be damaged.Check
the specification of the connected
equipment.When the current is above 10 mA,
connect an external resistor R2.

 1st trial to connect stepper motor failed when the motor only vibrate and not
linearly moving.
 2nd trial tries with different variable for coding such as delay time, but still vibrating
only.
 Try amplified voltage using “Darlington Pair”, 2 transistors that act like a single
transistor but much higher current gain.
Figure 13: Darlington Pair Circuit
 Use more than one power supply each 3 (actuator, forward, & backward move by
hardware)
 Need Darlington Pair circuit to amplify voltage because ARDUINO DUE cannot

mentioned earlier in chapter 4.3. Here are the lists of minor/work done in details.
5.1 SELF-LEARNING
About self-learning, throughout my internship here, a lot of websites I have visited for my
studies and the hands-on accomplishment report for my references. Before I started
anything, I have to study theoretically first, fundamental and anything related for better
understanding.
5.2 MEETING
A meeting is a gathering of people to brainstorming or exchange information, plan join
activities, decision making, or actions that have been agreed. In the meeting I had attended,
I learned how the professional meeting has been conducted. It is good experience for me
every Thursday we discuss and inform anything related last week progress, next week target
besides any highlighted issues to be mentioned in meeting to the lecturer and the others.
5.3 PRESENTATION
Presentation for me especially in an engineering environment is the best practice to
convince people. Its needs a perfect preparation for perfect outcome. So far I have a lot of
opportunity to make a presentation during my internship for example during the weekly
meeting both for progress and final presentation. For me these are most valuable
experiences to gain here all about confident level, the way to express the idea, and sharing
great ideas. All the cultivate feedback from my presentation is a part of learning process to
be better for future’s working/study environment.

  • 6. KEIO UNIVERSITY Page 6 3.0 UNIVERSITY INFORMATION 3.1 UNIVERSITY OVERVIEW Keio University is a private, comprehensive higher education institution located on six campuses spread across the Greater Tokyo area. It offers an environment of academic and research excellence in a wide range of fields, and includes a university hospital. Founded in 1858, it is Japan’s first modern institution of higher learning and over the last century and a half it has established itself as a leader in Japan through its continued commitment to education, research and medicine. Keio has its origins in the school of Western learning established by Yukichi Fukuzawa, a school which soon evolved into a major center of learning. As a highly respected educator and intellectual, Fukuzawa was one of the pioneers of modern Japan. He aspired for Keio to become a model and leader of society, stressing the importance of learning that is based on jitsugaku, or “science”. In today’s changing world, Keio upholds its founder’s spirit of science as it continues to fulfill his aspiration. 3.1.1 CAMPUS INFORMATION Keio University is a comprehensive academic enterprise with six major campuses in Japan, along with a number of affiliated academic institutions on or near these campuses. In addition, Keio University also operates a high school in New York. Since its inception, Keio has continued to pursue Yukichi Fukuzawa's spirit of jitsugaku, which holds that one should not just acquire information from book learning, but should learn from real-life experiences in order to apply viable solutions to actual problems. Keio continues to pursue jitsugaku today, fostering forward-looking thinkers at its six major campuses.
  • 7. KEIO UNIVERSITY Page 7 Figure 1: Yagami Campus Figure 1 shows Yagami campus of KEIO’s situated on a hill adjacent to the Hiyoshi Campus, the Yagami Campus was built in 1972 as the home of the Faculty of Science and Technology and the Graduate School of Science and Technology. This campus houses the latest in high- tech facilities for the education of tomorrow's scientists and engineers. 3.1.2 KEIO’S HISTORY Keio University traces its beginnings to the original Keio Gijuku, an institution of Western learning unlike any other in Japan in its time. Founder Yukichi Fukuzawa (1835-1901) was a man of uncommon courage, vision, and wisdom who defied the established powers of the time and pursued knowledge above all else, endeavoring to understand the society and morals of 19th century civilization in Europe and North America. His beliefs were very progressive in a Japan that was just beginning to awake from centuries of isolation. His convictions and deeds made an indelible mark on the country that would, barely more than a century later, become the second-largest economic power in the free world. Since its founding in 1858, the history of Keio University parallels the history of Japan's modern era. The vision and clarity of founder Yukichi Fukuzawa's original teachings have held up well for nearly a century and a half of serious academic inquiry in the service of Japan's development and modernization. Fukuzawa believed that Japan's only choice for catching up with Western technology and social organization was to "always strive for progress and enlightenment, and provide the academic and moral education needed to create a generation of wise and capable leaders." To this end, Keio University has continued to provide intellectual leadership that addresses the issues facing Japanese society in its quest for development, transformation, and modernization. As we face the challenges of the post-industrial era of the 21st century, Keio continues to uphold the pioneer spirit of its founder in his pursuit of peace, prosperity, and progress.
  • 8. KEIO UNIVERSITY Page 8 3.2 UNIVERSITY MISSION Keio University is not merely a place for academic pursuit. Its mission is to be a constant source of honourable character and a paragon of intellect and morals for the entire nation and for each member to apply this spirit to elucidate the essence of family, society, and nation. They will not only articulate this essence in words, but also demonstrate it in their actions, and by so doing make Keio a leader of society. 4.0 GENERAL STATEMENT OF THE TRAINING 4.1 INTRODUCTION On 16th June 2014, I came to FACULTY OF SCIENCE AND TECHNOLOGY, YAGAMI campus, KEIO UNIVERSITY to report as a practical trainee/student in Mechanical Engineering Department. Together with other practical trainee/student from the same Faculty of Malaysia Japan International Institute of Technology (MJIIT), Universiti Teknologi Malaysia had gone through the internship here about four weeks. We were given a short brief about department organization and functions by International Student Department. Then we were divided accordingly into different laboratory provided earlier. I have been placed into MEMS (Micro Electro Mechanical Systems) LABORATORY under supervision of Assc. Prof. NORIHISA MIKI, an Assistant Professor in Mechanical Engineering Department. 4.2 FACULTY & LABORATORY 4.2.1 CAMPUS GUIDE The students of the Faculty of Science and Technology spend their 1st and 2nd year at the Hiyoshi Campus and 3rd and 4th year at the Yagami Campus.

  • 11. KEIO UNIVERSITY Page 11 4.3 SCOPE OF WORK, TRAINING AND PROJECT CARRIED OUT Below are my activities during the Industrial Training from 16th June until 11th July 2014 at KEIO’s University: 4.3.1 MAIN TASK/PROJECT Senpai Mr. Ishizuka (PHD student) Project/Thesis about “Tactile Display for Stiffness Distribution with MR Fluid”  Focus study:  ARDUINO DUE board with ARDUINO programming language to send command  Linear Actuator comes with 5-phase and hardware (driver)  Objective :  The current mechanism manually, thus want to make it automatically functioning according to the command receive. 4.3.2 MAIN IDEA 1) How did I get the intention about MR fluid? I have heard about MR suspension systems before, MR is in fact a carrier fluid, usually oil, which is filled with micrometer-sized magnetic particles. When subjected to a magnetic field, the magnetic particles inside increase the fluid's viscosity, rendering it viscoelastic solid. Usually, a MR suspension system is made of four magnetorheological struts or shock absorbers, a sensor set and an electronic control unit (ECU). These technology were used by well-known German manufacturer Audi, with its introduction car model TT & R8. Figure 4: Supercar of Audi R8 Sports Edition For instance, in Audi TT's case, the driver can choose between "Normal" and "Sport" programs by flipping a switch and the system reacts accordingly, providing different damper response. ***Please Refer Appendix A for full article about MR Fluid 1 1 1 1 1 1 1 1 1 1
  • 12. KEIO UNIVERSITY Page 12 2) What is ARDUINO DUE board and ARDUINO programming language? The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet). It is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. Unlike other Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I/O pin could damage the board. Figure 5: ARDUINO DUE board The Arduino Due can be programmed with the Arduino software. From figure 5 shows either of the USB ports can be used for programming the board, though it is recommended to use the Programming port due to the way the erasing of the chip is handled: Programming port: To use this port, select "Arduino Due (Programming Port)" as your board in the Arduino IDE. Connect the Due's programming port (the one closest to the DC power jack) to your computer. The programming port uses the 16U2 as a USB-to-serial chip connected to the first UART of the SAM3X (RX0 and TX0). The 16U2 has two pins connected to the Reset and Erase pins of the SAM3X. Opening and closing the Programming port connected at 1200bps triggers a “hard erase” procedure of the SAM3X chip, activating the Erase and Reset pins on the SAM3X before communicating with the UART. This is the recommended port for programming the Due. It is more reliable than the "soft erase" that occurs on the Native port, and it should work even if the main MCU has crashed. Native port: To use this port, select "Arduino Due (Native USB Port)" as your board in the Arduino IDE. The Native USB port is connected directly to the SAM3X. Connect the Due's Native USB port (the one closest to the reset button) to your computer. Opening and closing the Native port at 1200bps triggers a 'soft erase' procedure: the flash memory is erased and the board is restarted with the bootloader. If the MCU crashed for some reason it is likely that the soft erase procedure won't work as this procedure happens entirely in software on the SAM3X. Opening and closing the native port at a different baudrate will not reset the SAM3X.

Motor cable required for connection (see Accessories) DC Driver input type motor only Features: High Torque Stepping Motors The PK Series 0.72°stepping motor offers high torque, our lowest vibration and noise. This motor is wound in the bipolar New Pentagon configuration and therefore, require a New Pentagon bipolar type driver. The New Pentagon configuration ensures that maximum torque is being generated by the motor on every step. The New Pentagon configuration also provides extremely smooth motion as well as maintaining torque and step accuracy regardless of the step resolution. Figure 7: Torque Characteristic ***Please Refer Appendix B for full article about Operating Manual Improved Torque This motor combines high torque and a compact size. Three frame sizes, 0.79 in. (20mm), 1.10 in. (28mm) and 1.65 in. (42mm), are available. The high torque motor generates approximately 1.3 to 1.5 times the torque achieved by the standard type.

Basically this software and the language is quite similar to the programming C/C++. Figure 8: ARDUINO development environment software & sample code I have my self-study about this programming language about 1 week and at the same time I have to know about ARDUINO DUE board each function. My senpai have been requested me to study how signal been received & send within computer and ARDUINO board and at the same time understand all the mechanism of each component of ARDUINO DUE board before proceed. ***Please Refer Appendix C for full note about ARDUINO PLAYGROUND
  • 15. KEIO UNIVERSITY Page 15 Oscilloscope An oscilloscope, previously called an oscillograph, and informally known as a scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time. Non-electrical signals (such as sound or vibration) can be converted to voltages and displayed. Figure 9: Oscilloscope with display Oscilloscopes are used to observe the change of an electrical signal over time, such that voltage and time describe a shape which is continuously graphed against a calibrated scale. The observed waveform can be analyzed for such properties as amplitude, frequency, rise time, time interval, distortion and others. Modern digital instruments may calculate and display these properties directly. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument. The oscilloscope can be adjusted so that repetitive signals can be observed as a continuous shape on the screen. A storage oscilloscope allows single events to be captured by the instrument and displayed for a relatively long time, allowing human observation of events too fast to be directly perceptible. Oscilloscopes are useful for looking at very fast changes in voltage over time, things that we could not measure with a multimeter. Usually when you make a measurement with an oscilloscope, you will see a line that stretches from one side of the screen to the other; this line is actually a graph of voltage vs time (fig 2), where voltage is measured along the y axis and time along the x. Oscilloscopes come in two varieties: analog and digital(I'll be using a digital scope in this tutorial). The controls on both types are basically the same; be aware that the digital scopes may hide some of there controls in a menu on the LCD display instead of using knob or button.
  • 16. KEIO UNIVERSITY Page 16 Pulse-Width Modulation (PWM)  Digital square wave, where frequency is constant, but fraction time the signal is on ( duty cycle )  By changing the pulse width, we change the average voltage seen by circuit ( pulse width modulation technique ) For example 10V ~ If duty cycle is 10%, only effective average of 1 volt Have 3 main characteristics:  Amplitude – amount of signal changes between on & off states  Frequency – number of times the signal repeat in given time frame  Duty cycle – proportion of on time to off time usually expressed as percentage. The simplest waveform to get an Arduino to produce is a square wave. The square wave (as the name suggests) simply cycles between the HIGH and LOW logical levels. Figure 10: Square Wave produced with oscilloscope Apart from the frequency of the wave, there are a couple of other main characteristic that we might want to modify: the amplitude (a measure of how much higher the HIGH level is, compared to the LOW), and the symmetry of the wave – the so-called duty cycle. We’ll leave the amplitude aside until next time – as that’ll require us to do a little more work; but let’s look at the duty cycle of the wave. The duty cycle is simply a measure of how much of the time our wave is at the HIGH level – compared with the total time of the cycle. So far all of our square waves have been symmetrical: with an equal amount of time spent in both states. This is known as a 50% duty cycle.
  • 17. KEIO UNIVERSITY Page 17 Connection & Operation The 5-Phase stepping motor need a driver to be successfully connected within controller (ARDUINO DUE). Figure 11: Motor driver Figure 12: Wiring diagram between controller, driver and motor ***Please Refer Appendix D for full view about overall Connection & Operation ◇ Input Signal Connection Signals can be connected directly when 5 VDC is supplied. If the signals are used at a voltageexceeding 5 VDC, be sure to provide an external resistor to prevent the current exceeding 20 mAfrom flowing. Internal components will be damaged if a voltage exceeding 5 VDC is supplieddirectly without using an external resistor.Example: If the voltage is 24 VDC, connect a resistor (R1) of 1.5 to 2.2 kΩ and 0.5 W or more. ◇ Output Signal Connection Use output signals at 24 VDC or less and 10 mA or less.If these specifications are exceeded, the internal components may be damaged.Check the specification of the connected equipment.When the current is above 10 mA, connect an external resistor R2.
