A new project has transformed a humble Arduino Pro Micro into a joystick with various knobs. The project is intended to be used in conjunction with a keyboard for making adjustments when gaming or creating music.

A new project has caught our attention on Instructables. Called the Arduino Keyboard Joystick Extender Box, the project utilises an Arduino Pro Micro, a joystick and four rotary knobs. Four potentiometers and an LED, along with network and USB cables are also called for to get the project working. Brad Gier, who posted the project on Instructables, then housed these components in a 3D printed case, the files for which he has provided.

Grier has built the project around Deej, an open-source hardware volume mixer for Linux and Windows. You can read more about Deej on GitHub. The project is screwless and so you must be comfortable using a glue gun to insulate the solder joints. Wiring the parts together looks finicky too, but this is all outlined in the project walkthrough.

Grier has also uploaded the Arduino code and Deej configuration file necessary to get the project working. It should be noted that you could use an Arduino Nano or an Uno instead of a Pro Mico, although Deej developers only recommend using the Nano and Pro Micro. Additionally, only the Pro Micro has a dedicated joystick connection.
