How would I control the flow of power from a DC bus to a H-bridge with an arduino uno? I don't want to generate power from the arduino to drive the motors.
In my mind I would like the arduino to control a varistor with a robot arm, but I know there must be a better way.
I don't have the exact specs on the h-bridge but I have an existing RC curcuit that works to control it - and I have a multimeter and have started to take voltage-drop measurements while operating and not operating for comparison with the curcuit I want to build. I am guessing that If I can create the same voltages than I can get the motors to run under arduino control (but I may be missing something - my software skills are much better than my hardware skills).
Also how do I determine the exact model and firmware/hardware version of my arduino uno. I think that may matter.
