Yash Savani aka codingAssassin has released code to control an RC Car using a PS3 controller, here is a quote from the source:
In this project I have provided the necessary code to control an RC Car using a standard Sixaxis, Dualshock 3, PS3 controller. If you haven’t already make sure you see the tutorial on how to get started at http://youtu.be/KO11kluoHMs.
PS3 Controller to Computer
The PS3 controller communicates with the computer using Bluetooth. The Processing code running on the computer, hacks this Bluetooth connection using the procontroll library (http://creativecomputing.cc/p5libs/procontroll/index.htm). The data from the BT connection is then processed and the processed data is sent via a serial USB using the UART protocol to an Arduino. This Arduino is the base transmitter.
Here is a video of the mod in action:Tweet this!
