6. Introduction
• “Arduino is an open-source physical computing
platform based on a simple i/o board and a
development environment that implements the
Processing / Wiring language. Arduino can be
used to develop stand-alone interactive objects
or can be connected to software on your
computer.“ ( www.arduino.cc, 2006 )

7. Introduction
• A physical Input / Output board
(I/O) with a programmable
Integrated Circuit (IC).
• Also including an Integrated
Development Environment
(IDE) for programming.
• The language itself is based in
C but is largely modeled upon
the www.processing.org
language.

8. Introduction
What is it used for?
• Physical Computing
projects / research
• Interactive Installations
• Rapid prototyping
What can it do?
• Sensors ( to sense stuff )
– Push buttons, touch pads, tilt switches.
– Variable resistors (eg. volume knob / sliders)
– Photoresistors (sensing light levels)
– Thermistors (temperature)
– Ultrasound (proximity range finder)
• Actuators ( to do stuff )
– Lights, LED’s
– Motors
– Speakers
– Displays (LCD)
– Relays

9. Introduction
Why Arduino?
• It is Open Source, both in terms of Hardware and Software.
• It is cheap, the hardware can be built from components or a prefab board
can be purchased for approx 25 Euro
• It can communicate with a computer via serial connection over USB
• It can be powered from USB or standalone DC power.
• It can run standalone from a computer (chip is programmable) and it has
memory (a small amount).
• It can work with both Digital and Analogue electronic signals. Sensors
and Actuators.
• You can make cool stuff! Some people are even making simple robots,
and we all know robots are just cool.

Command
// Comments
1) int Global Variables declaration: i.e. integer
2) setup() Setup of devices, pins and sensors
3) loop() Programme routine
void Function declaration
pinMode(pin,mode)
funzione di configurazione di un piedino
Arduino, in modo che sia utilizzabile come
INPUT o come OUTPUT
digitalWrite(pin,level)
invia un comando di output sul piedino
selezionato (pin) di tipo digitale, pe cui 0 o 1;
in sostituzione dello 0 e dell’1 si possono
utilizzare le costanti LOW (0) e HIGH (1)
delay(second)
funzione utile per introdurre un dalay (attesa)
tra una istruzione e la successiva, il
paramero second è esperesso in millesimi di
secondo.

24. Programming
Analog and Digital
Temperature sensor that convert in a voltage signal, and Arduino can acquire voltage
value between 0 and 5 volts.
This values are different from the HIGH and LOW that characterize digital signals,
because they can take any value between 0 and 5 volts. 0.3 volts, 3.27 volts, 4.99 volts
are possible values.
One small hardware part inside the microprocessor that comes with the Arduino I/O
board is dedicated to translate analog voltages into these values, it is the Analog to
Digital Converter also called ADC.

25. Programming
#define DHTPIN 4 // digital pin
Serial.begin(9600); // serial communication ON at 9600 Baud Rate (bits/sec)
dht.begin(); // external library
pinMode(O0, OUTPUT); // declare digital sensor as output (relay)
pinMode(I0, INPUT); // declare digital sensor as input (button)
digitalWrite(O0, LOW); // change the state of digital channel
int val = digitalRead(I0); // read the digital channel
rada = analogRead(1); counts 0-1024 // read the digital channel
rad1=(rada*5)/1.024; millivolts 0 - 5000
Serial.println("PUSH"); // print a string in Serial Monitor
delay(1000); // delay for the loop
