Software Required: (click to redirect)

• Arduino IDE
• Bluetooth Car Controller App

Note:

1* Arduino UNO with cable to upload the code.

2* But after the finished project, DC connecting cable will be used to power the circuits. Also +5V pin in Arduino UNO can ve used to power the motor driver and the Servo motor. +3.3V from the Arduino board can be used to power the bluetooth module and ultrasonic sensor.

3* Sound button in the mobile app can be used to make the robot go into automatic mode, and forward button can be pressed(for more than 2 seconds) to generate the interrupt and turn the robot back to RC mode.

4* In order to change your bluetooth module name or password or any other parameter checking, search about “AT bluetooth module commands”.
