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 wonder how I'd do that... |
