This video also covers the way WS2812B single wire addressable LEDs work, and why they are horribly demanding of processor time unless it has a dedicated serial driver built in.
It's notable that the high speed data requirement means that this unit has two microcontrollers. One for time and infrared functions, and one to bang out the 800Kb/sec data to the LED string.
I also tested it with standard WS2812B LEDs and the bare module could be used to run other strings. I'm guessing the controller may scale back the intensity to keep the current manageable, as the LEDs are capable of passing 60mA each on full intensity white.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm
This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
