2. OBJECTIVE - I
 To provide solution for “People With
Disabilities” and to enjoy their
“Smart Move”
How to provide?
Solution!!! Proposed in smart way

3. OBJECTIVE-II
Implementation
Process
To produce a prototype for Stepper
Motor interface with Android Device
via Arduino Board.
To interface a GSM modem.

4. What is Arduino?
• Arduino
is
an
open-source
electronics prototyping platform.
•
It's intended for developers for
creating interactive objects or
environments.

5. NEED FOR ARDUINO
in
Interfacing Stepper Motor
with Android
4

6. • To trigger any hardware peripherals
from Mobile we need of driver IC to
redirect the PWM signal.
• But not especially using of Arduino
there are multiple choice
Ex: Beagle Board
• Here we use Arduino as a mode.

Embedded ADK Board is on processing

8. Establishing Communication
• In an Android-powered device
accessory mode is detected
an
• The
accessory
can
query
the
device's interface and endpoint
descriptors to obtain the bulk
endpoints to communicate with the
device.

9. Contd..,
• The first interface is for standard
communication
while
the
second
interface is for ADB (Android Debug
Bridge) communication.
• Find the first bulk input and
output endpoints, set the device's
configuration to a value of 1, then
communicate using the endpoints.

10. System Functionality
• A PWM signal are predefined and
generated by android progress bar
component
• when the progress status changes
the functionality are defined to
Hardware via a Arduino Board.
• Hence the direction of the stepper
motor is controlled via the same
component.

13. Conclusion
• We cant predict the birth nature
but we have technology on hands.
• That’s triggered in our proposal.
• In future this is a product
creates a place in People
Disabilities heart.
