MarkT,
Thanks for the clarification on the motor and the terminology, I'm still learning. Some of the scooter guys call them ESCs, so that's what I called it. To me it's a 'driver', since the control part will be taken care of by the Arduino. At least that's how I learned the terms when I was building my CNC and RepRap.
I'll keep studying the two links above and report back here with progress, if any.
Thanks,
Gyv
