Reverse engineering an 8×8 LED grid for Arduino
Recently I’ve been doing a lot of work with LEDs. For an upcoming class called DevFest I’ll be leading a group of ~60 coders in their first steps with Arduino and robotics. This course includes a getting started grab bag of fun electronics, including an LED panel. None of the parts came with any kind of documentation or API. I had to do some reverse engineering to figure out how they worked. This LED panel was both really frustrating and really fun to figure out. How I did it and how you can too
