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

At it’s heart, it’s a straightforward design, using a linear rail and a leadscrew driven by a stepper motor. Control is via an Arduino Nano, with a few push buttons and a 16 x 2 LCD display ...

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.

YouTube channel How To Mechatronics has created a great tutorial with full instructions on how to create your very own Arduino powered 3D wire bending machine.
