Custom Android Application and Arduino Based Bluetooth RC car

A modified RC car. It is controlled by an Arduino Uno and Arduino's motor shield. The communication between the phone and car is done through a Bluetooth module connected to the Arduino Uno. The Application is custom made. Front and Back lights were added to the RC car. To control the car, the phone sends an ASCII character to the Arduino. Depending on the character, the Arduino makes the motors rotate. To control the car, buttons are used. But the phone's accelerometer can also be used (pretty difficult to operate in a small area).
