Yeah I am not sure why my comment got flagged for moderation. That happened when I went to edit the comment...I may have accidentally hit the Flag link, it is right next to the Edit link. It is back though.

I am pretty sure I actually already tried switching those pin numbers and the behavior didn't change; however, I tried several things so possibly didn't quite do that exact thing. The behavior certainly suggests those two pin numbers are switched, so I will revisit switching those pin numbers. The motor actually does stop when you push the switch on the potentiometer, so that part is working correctly.

If that doesn't work I will switch out the motor driver (bought 2) and nano (have plenty of those). My wife is looking forward to me getting this completed, she currently uses a hand cranked ball winder.
