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.

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 Nano Every is a pin-equivalent substitute, so previous code and wiring will still work. Arduino has also swapped out the Nano's mini-USB connector in favor of micro-USB.

In terms of the hardware, this robot uses an Arduino Nano as the brain, two motor drivers to control the DC motors, a wireless transceiver module to receive signals from the transmitter device ...
