I have an ardumoto connected to my uno. I have 1 motor on A and 1 on B. I am powering with a 9v drill battery. The issue I am having is not understanding the directions…
From what I am reading to me it seams if you set dir_a, HIGH it should spin 1 way then if you set it LOW it should spin the other way… What I am seeing is if I set either to LOW it is off… HIGH is on… and B is one direction and A is the other… Is this correct?? If so is there a way to get motor a to spin clockwise while motor b is spinning counter clockwise?
