I am trying to control a Black & Decker VersaPak screwdriver with my Arduino motor shield. When I connect it, the board resets. The VersaPak is 3.6v, I'm not sure about the amperage, but it's Ni-Cd. I hacked the device with the power going to the + and ground with the motor going to A+ and A-. Am I putting too much power into the board? If so, what circuit should I be using? Otherwise, what I am I doing wrong? I am using 24 gauge wire, is this too light weight?
Thanks in advance for your help. --jack
