Collin Cunningham’s videos remain golden! In Circuit Skills: LED Matrix he talks about LED matrices and how to control the LEDs with a multiplexing IC. He uses it to make a mini game machine!
Many an experimenter, hacker, tinkerer, & maker have heeded the call of the mighty matrix – and it’s no mystery why. A small army of LEDs elegantly wired in grid formation would be difficult for anyone with an appreciation for electronics hardware to pass up – even after considering the sometimes daunting wiring job that stands as prerequisite to entry.
Needless to say, I had a lot of fun working with LED matrices for this installment of the Circuit Skills series. Many folks have published code for their matrix projects and it was great to be able to try some of them out.
