I took a servo and basically converted it to a DC motor by taking out the brains of it essentially. I think that part is okay, now I am unable to control them at all from my phone. I have an Adafruit v2.3 motorshield and have connected my dc motors/servos to that. Using bluetooth I have been able to connect via my phone and control a 3 wire servos position. Now I would like to control the direction at which my dc motor/servo spins. So far I have not had success. Anybody have any suggestions as to why this would be happening?
