Is using a relay and some switches a standard way to reverse a motor or is the preferred method to use a H-Bridge? The circuit for reversing a motor with a relay looks like this:
Note that this circuit is just to show the relay and motor connections. The main control would be the coming from a PIC not an op-amp.
Me and my teacher are having disagreements about the best way/standard/preferred way to reverse motors, so what would engineers do?
