U8g2 is used for controlling the display and FastLED is used for controlling the LED strips, with some hacks to make it work with RGBW LEDs.
The firmware is built using PlatformIO.
Source code, mechanical design files, and further build information are available at the GitHub repository.
Sleek little user interface for this one, neat!
