I recently helped my friend Clive “Max” Maxfield with his 12×12 ping-pong LED array by making a simulator which runs on the Arduino GUI so that anyone can create and test a program to run on Max’s LED array.
The idea is that people can develop their own application and test it using my simulator, then submit it to Max so he can run it on the real 12×12 LED array. He will then post a video of the submission!
