If you’ve never worked with wiring before or you’re new at it, having step-by-step instructions is nice. ThePsychotenuse created an illustration to follow, showing how everything will plug into and be wired to your Raspberry Pi device. If you’d rather watch a video of it, you have that option too. As for what you need, you’ll want to get your hands on the USB soundcard, eight push-to-connect buttons, and eight LED lights.
You can pick up buttons for quite cheap, as a set of 25 will cost you under $10 from DigiKey. The lights are optional, but you’ll probably want those as it’ll be tough to tell what you have on or off without them. The YouTuber gives you the full breakdown of parts along with the program that needs to be installed onto your Pi for everything to work. This isn’t a very expensive project to try if you already have the Pi, so that’s a nice bonus.
This project will be for people interested in making their own music as a side hobby. Professionals would probably be better suited just buying an actual looper versus making one, but it’s not a bad idea if you have an extra Pi lying around already.
