I am finally getting around to playing with my GoPiGo.
All is well, except that the motors don’t go in the same direction. And yes, my cables are alternating, black, white, black, white.
I switched them to white,black,black,white, and now they’re going in the same direction. However they don’t seem to get the same amount of power. At least not consistently. My GoPiGo goes in a sinuous pattern instead of going straight.
