If you want to learn:
- Draw out the schematic.
- Probe the circuit in various places with your oscilloscope and add that information as notes to the schematic.

If you want to customize it:
- Replace U3 micro with an arduino and a few pots or buttons for inputs
- or, buy a few buck modules with adjustable current limiting and connect a pot to each to have distinct LED string control
- or just get a LED light with color adjust functionality already built in

I reckon I can shoehorn an ESP32 into it somehow, and control it with BLE "GATT" commands, which I've been playing with for a few weeks. I wonder how I'd do that...
