Before I start, Id just like to clarify that the only programming experience I have had is with VB. As such, I found picbasic's programming protocol rather easy. However, I have had no luck in getting my microcontroller to function.
My plan is :
1) Whenever the user presses a button on the controller, a signal is sent to any of the inputs which in turn causes an output to pulse.
2) The pulses for movement differ and are transmitted to the car using an infrared transmitter.
3) When they reach the car, these pulses are decoded and the proper output becomes active high and the car runs in the proper direction.
Im sorry if Im asking a bit too much, but I really need this to get to work as my project is due by friday.
thx
