Many people are unaware of the powerful bluetooth capabilities possessed by Arduino. What better way to learn than by modifying an existing remote control car so that you can control it using your smartphone over bluetooth! At a basic level this project works using a H-Bridge motor controller to enable the Arduino to have control over the remote control car’s motors. A bluetooth module allows the Arduino to receive messages from an Android phone over bluetooth which can be used to control the car. Very cool!
