hey,all of you.do you know how to make self-learning remote control car.For example if i control the car using remote control and let it move to 1 track or 1 around.when i press a switch ,it will follow back the previous track that i control without controlling by user.The problem is i don't familar with the PIC16F84..i don't know how to store the previous instrcution that i control the track and save it in memory..any idea.thanks..
