Schematics

Controls Schematic

This is the schematic for all of the electronics. Its kind of complicated in the center of the diagram, however the bluetooth dongle receives what the PS3 controller is telling it and it sends it through the Arduino USB host shield that is plug in to the Arduino UNO which tells everything else that to do.
