To control the motor, [Gerald] is using an Arduino Nano coupled with a ULN2003 Darlington array which live on a routed PCB he made with his school’s Qbot MINImill.

The motor is controlled via an Arduino Nano and an A4988 stepper motor driver. However, that only covered the mechanical side of things.

Arduino has been used to control a stepper motor driver a MIDI interface, scanner parts and basic keyboard to great effect, check out the video below to learn more. Watch this video on YouTube.
