Description
ATtiny LED Matrix Display Badge
Have you ever thought of making a badge-sized PCB that can display some letters, numbers, etc... or your name?
In this project, I will be showing how I built a badge-sized ATtiny85-based LED matrix display (5x4 matrix). I have used Charliplexing technique for driving 20 LEDs using ATtiny85.
This project is open source. If you would like to build your own, all of the resources are available in the GitHub.
