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.

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.

Then he found the very affordable 28BYJ-48 stepper motor. After some experimenting, he came up with a smooth moving robot arm with four steppers controlled from an Arduino Mega and A4988 stepper ...

Created using 3D printer parts, a handful of stepper motors, and an Arduino Nano development board, the wire bending machine can be programmed to create a wide variety of different shapes and angles.

The Arduino Nano Every is faster, cheaper, and has more memory than it's predecessor, but what is it, and what can you use it for?
