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.

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.

Most of my Arduino code was readily available on the Arduino website and is free to download at GitHub. Near the end of my video I will show you how to build a MIDI controlled stepper motor in 40 ...
