This code shows an generated, never ending, random and organic animation on the led-panel of the IKEA Frekvens lamp. It is using the noise-generation of the FastLED library to generate the pattern. The pattern is then mirrored 3 times, to have some kind of kaleidoscope effect.

The buttons change the brightness and the parameters for generating the noise-pattern. Using the easyButton library for the buttons.
I used a Arduino Nano for this.
Using the great work of @frumperino: https://github.com/frumperino/FrekvensPanel Could not have done it without this.
