Yeah I'm not sure how to drive it either. I'd like to use any sp32 but that only has like 40 gpios max. I think you can set up logic gates or something I don't

- evan_ 5y agoLook into addressable leds like the WS2812... you can wire them up in series (or buy them pre-soldered on tape) and you can control hundreds of RGB leds independently with just two wires. Adafruit sells tape as well as matrices of the stuff which might be what you’re looking for
- evan_ 5y agoif you’re dead set on controlling individual LEDs look up “charlieplexing” which will let you use n pins to control n^2-n LEDs
