Yea sounds like a good idea, I figured out how to do if then commands and I think I just figured out why my buttons were not working. I didn't signify a b0 register as a byte. Anyways, what I will need most help in will be the serout and serin to connect to the chip on the car to make the car move forward, back, etc.

And can I use rumble motors from an xbox 360 controller for my main forward and reverse motions? can these be controlled like a servo or not? see, there is a requirement that we have to make the vehicle stop when at a certain time. The faster it stops the better.

thanks for all your help guys!
