ArduinoCar

Controlling an Arduino car using android and wifi direct.

Protocol

The phone and arduino communicate with this protocol:

>TypeIndexDatas<

Where:

• > Indicates the start of a command
• Type can either be M (motor) or S (servo) [1 byte]
• Index is to specify which motor/servo to control [1 byte]
• Datas are speed and run mode for motor, angle for servo [multiple bytes]
• < Indicated the end of command

Example:

    // Set the motor at index 0 to speed 200 and run forward
    byte[] cmd = {'>', 'M', 0, 200, 1, '<'};
