HackSpace Magazine Issue 55: Build a guitar games controller #CircuitPython @HackSpaceMag @Raspberry_Pi

HackSpace Magazine — Issue 55 shows you how to make a guitar games controller with Raspberry Pi Pico and CircuitPython.

In this tutorial, we’ll build our own controller. If you don’t have a broken 3D-printed guitar, don’t worry: this is just what holds everything together. You could use almost anything. The simplest would be a wooden plank, but you could be
creative. An old tennis racket would give classic air-guitar vibes, or you could cut a guitar shape out of sheet material (such as plywood or MDF) with a jig-saw. If
your really want to go the whole hog, you could also 3D-print your own guitar –
the design files are at thingiverse.com/thing:486731, but we wouldn’t recommend using the same alignment that we used.

Since our game takes input from the keyboard, we just have to set Pico up as a keyboard, then we can get our program to send keystrokes to the computer and
the game will interpret them as though they’d come from any normal keyboard. It’s actually very easy for some microcontrollers to behave like keyboards, and you can do this in a range of languages, but we find CircuitPython to be just about the quickest and easiest option for this. Since Wireframe’s game is also written
in Python, this mean  that both the game and controller are in a single language, which helps keep things simple.
