OBJECTIVE - ITo provide solution for “People With Disabilities” and to enjoy their “Smart Move”

How to provide?

Solution!!! Proposed in smart way

OBJECTIVE-II

Implementation Process

To produce a prototype for Stepper Motor interface with Android Device via Arduino Board.

To interface a GSM modem.

What is Arduino?• Arduino is an open-source electronics prototyping platform.

• It's intended for developers for creating interactive objects or environments.

NEED FOR ARDUINO in

Interfacing Stepper Motor with Android

• 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.

ARCHITECTURE

Embedded ADK Board is on processing…………………Arduino replaces the place

6

Establishing Communication

• In an Android-powered device an accessory mode is detected

• The accessory can query the device's interface and endpoint descriptors to obtain the bulk endpoints to communicate with the device.

7

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.

8

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.

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 that creates a place in People with Disabilities heart.
