What I’m Building
A mini concert for my desk. I’m building an 8x8 LED matrix that reacts to music in real-time.
Why I Chose This Project
I’m a software dev, I want to learn hardware and I thought this would be a great place to start. Mainly because this project will teach me the basics and be quite simple to make something light up and achieve a small milestone.
