LED Matrix Display Badge

Make a simple but challenging badge with an LED matrix display and an ATtiny13!

Build a cool LED matrix badge with a custom sliding text string, using a dirty cheap microcontroller (the project is built around the ATtiny13 but if you have other spare ATtinys it will work fine) and other common components. There is a proposed PCB you can order, but the full sources are provided so you can make one on your own.”
