I am looking to upgrade my first robot which is built from the LMR Starter Bundle. I to start out I would like to upgrade to 4 motors. Currently I only see the A & B pins for motor control. The motors do not need to be independently controled, I only need to be able to control 2 at a time. Is this doable?
Also, I eventually want to upgrade to bigger motors, would it be easier instead using 4 triacs or relays?
