Hey guys!
I've wired a floppy disk to the UNO using 3 wires (one for ground).
The code I had been using that let me control it (somewhat) through the serial monitor came from here: http://www.instructables.com/id/floppy-drawbot/
That's great to move it a certain pre-determined amount of steps, but I'm trying to add manual control.
I'm having trouble getting it to work with a potentiometer though.
