While browsing Adafruit’s Thingiverse designs, one caught my attention – 32×32 Pixel Display . I always love those RGB Matrix displays, and having one just to display some pop culture images and animations, was an awesome idea. This project takes the idea from Adafruit, but uses a Raspberry PI Zero W instead of a Feather RP2040 and […]

RGB LEDs consist of a red, a green and a blue LED conveniently encapsulated in one package. Theoretically one such should be able to produce any colour of the rainbow, but I have restricted my project – for reasons explained later – to just red, green, blue, cyan magenta, yellow and white. The project uses
