“A home made LED matrix controlled by a Raspberry Pi Zero for animated pictures and disco lights.
The beginning
I stumbled upon a video made by Andrew Oakley of an inexpensive LED matrix that he’d made using a Raspberry Pi. I thought it was pretty cool and decided I’d like to make something like that myself. I have pretty much followed the essence of his build as described here. So there probably isn’t too much point in me going over everything in great detail. The main difference between his project and mine is that I’m using a Raspberry Pi Zero and I’ve gone for an extra strip of LEDs, making a total of 150 rather than his 96. I wanted it to be a little higher res as our front window is almost directly on the front street and felt that the picture quality might suffer from such close range.
Setting up the Pi
The first thing to do was to follow this tutorial on setting up the Raspberry Pi Zero to operate a neopixel string of LEDs.”
