PS3 Controlled Car

I am completely new to arduino's but have always wanted to learn.

I purchased the following items

Arduino Car

and the USB Host shield

and a PS3 Navigation Controller and working bluetooth dongle

I have managed to successfully connect the PS3 controller to the arduino and the board is receiving the input values. I have no background in coding and I can't seem to find a decent tutorial or even a course that would show me how to take the joystick and key inputs and have them translate to wheel movements.

Ideally I would like the joystick to control forward and backward movements. The car kit doesn't have actual steering so left and right movements of the joystick would require some sort of speed adjustment to the corresponding left and right motors to make the car turn.

Any assistance with the coding would be greatly appreciated.
