How does it communicate with pc? what did you use for input??

He would use USB for the connection; but to make the parts know when they are being used, he would wire them up to a USB controller circuit board, then configure the circuit board original buttons, on his pc

how do the pedals and wheel relay information to the computer and tell it what to do?
looks like an interesting project, can you explain a little bit more about what you're doing in each step?
