Inside there’s a pair of 3D-printed ring gears that are each driven by a stepper motor and controlled with an Arduino Nano and a real-time clock module.

In [Jeremy’s], he’s gone with two inexpensive $2.00 stepper motors. The RC is done using a keyfob transmitter with a receiver board wired into an Arduino Nano’s analog pins.

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.

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.
