Simple docker-based web controller for Adafruit's neopixels made for raspberry pis and similar SBCs.
Built with Adafruit CircuitPython Neopixel, flask and iro.
docker-compose up starts up tiny flask server on the raspi. The web controller is then available at http://<ip -adresse>:5000.
Calculation of HSL to RGB+W values are done on clientside due to the limited computing capacity of the PI. Special thanks to SaikoLED
I wired the neopixel with a Diode as in the official adafruit tutorial
