Nice! I put neopixel strips in all my model train city buildings and have an esp32 program that control each building, floor, and room. I wanted to add a skyscraper with only white lights, so I glued photo cells to a few pixels and attached relays to control 12 v white led strips, so now I can light the lights with the same fastled code. I need to get some of your boards now.
That sounds cool. I'll have a video up soon on the relay board, but basically just make sure they're low-side-active relay boards with their own flyback diodes and drive transistors. The ones I show in the teaser at the end came from AliEx and had jumpers you could change to make them high or low control active. Send me a pic or video of the result and I'll feature your project in a future video.
