hi all need help: I built a tank with infra-red detector. I’ve implemented it in such a way that - when the detector (which is connected to external INT0 - pin2) - is switching from 1 --> 0 - an interrupt occurs. inside the ISR (interrupt service routine) - i've just rotated the motors backwards …

What is it that is supposed to stop the motors rotating backwards when the tank has moved sufficiently far away from the wall?
