I've done a lot of programmable LED projects (keyword Neopixel or WS2812) and by far my favorite hardware has been this little raspberry pi pico board that takes care of the power requirements for you, a USB-C cable can supply 3 amps, powering one or two hundred LEDs with ease. There's lot of Arduino boards that let you program a few neopixels, but supplying power for lots of them is usually the annoying part. https://shop.pimoroni.com/en-us/products/plasma-2040 https://shop.pimoroni.com/en-us/products/plasma-2040 https://github.com/pimoroni/pimoroni-pico/tree/main/micropython/examples/plasma2040 https://github.com/pimoroni/pimoroni-pico/tree/main/micropyt...
