    Not to be too critical, because I’m sure it was fun, but was the arduino needed? I can imagine doing this much simpler with only a few parts I have just laying around. POT, DC motor, switch, battery holder… Can’t imagine needing much more. Maybe a simplified version of this would be fun to start young kids with?

    The reason I used an arduino was because I didn’t have a standard gearmotor and I needed a motor driver to control the stepper. I could have done it with just a motor and a switch, but with the motors I had it would spin way too fast. I also wanted to be able to add other things (buzzers/leds) to show when it was done.
