On 03/03/2021 I discovered that my local dollar store had $4 strips of RGB lights. They could be controlled with an IR remote, similar to an old TV.
I purchased it, and immediately stripped the shrink wrap off the controller. I discovered 2 things from this:
- If I want to control the the RGB strip, I'm going to need to remove it
- It's actually pretty simple!
1 is because it has no reverse power protection as far as I can tell, so applying power to any of the colors could cause the microcontroller to turn on, and then switch everything to white - Spreading the power based love, as it were. 2 is because the way it works, well, is simple! You supply 5V on one line, and ground the color you want. Presumably you could use somthing akin to PWM to control the intensity.
