Yes sorry I meant autonomous;) The circuit board transmits the radio signal from the controller to control to servos, 1 at the top is to turn the wheels and the bottom one is to make it go forward and backwards. I don't care for the remote controller, I want to ditch it and just use it with the arduino and make a program to automatically do a preprogrammed course. I'm planning to use the arduino to just tell the motors where to go with a preprogrammed track. I plan to use the car as a robot and for the steering I can add a second motor in the code and create custom turns to do.
Are you going to measure the time (preset delay) in which the car turns or use an encoder to track the distance of how far the car goes to then decided when to turn?
