Hello LMRians, This is a PID implemented line follower using an Arduino ATmega168 clone, Pololu QTR-8RC sensor array, a Pololu TB6612FNG Motor Driver, and super fast and zippy pololu micrometal gear motors. ( 30:1 Gear Ratio, MP version)   PID? Is that the name of a super hero or a mega villain? It's kinda both. If you manage to tune the parameters perfecly, you'll be fascinated by the results that follow, however, at the same time, you're gonna have some sleepless nights if you get it ...
