PID Control Demo: Proportional, Integral, Derivative

For those not in the know, PID stands for proportional, integral, derivative control. I’ll break it down:
P: if you’re not where you want to be, get there.
I: if you haven’t been where you want to be for a long time, get there faster
D: if you’re getting close to where you want to be, slow down.

Motors, in general, don’t start or stop on a dime. So it’s easy to overshoot, undershoot, whatever. PID allows you to dial in those three concepts with numbers

Thanks Warlax 56 for simplifying the PID
