SophieHere's a recent project. This is my Workbench Lighting Controller. It has 10 12V dimmable channels. I designed it as an exercise in SMD circuit design and construction as well as using a microcontroller directly embedded. It worked great, except the LEDs misbehave a little sometimes. I wrote it up as an article for DIYODE magazine, you can find the instructions here https://diyodemag.com/projects/workbench_lighting_controller (And at hackaday dot io as soon as I get around to writing it up there).
