I am looking for help or advice on how to create an LED controller circuit. What I am envisioning is an circuit 1.5" in diameter inserted in a cup with a translucent lid to change colors and go off when rotated. With a 5-10 degree dead spot where the LED’s are off. I would be looking at a few thousand boards. I want the same functionality and form factor as the Everbright board (https://theeverbright.com/) without the automation and animation. Just simple turn to turn on and change colors. I would prefer free rotation rather than limited rotation. Being able to rotate as many times as desired but this is not a “must have”.
I wish to make several of these boards for my grandkids and not for any commercial application.
