No Arduino required. (In fact, it may ruin your Arduino) Thought this was pretty cool. Take any two wires from a stepper motor. Connect them thru an LED. Spin the stepper by hand. Watch the LED light up :smiley: Note: I've only tried with a 5-wire stepper. Doesn't matter which way the LED is turn…

Have you tried connecting two stepping motors together?

You spin one and the other turns. :o

Also works for regular DC permanent magnet motors.
