This projects provides the code for the following deej volume mixer: https://www.printables.com/model/867600-deej-volume-mixer-arduinoledrgbmusic-control
To support the buttons, the following deej fork is required: https://github.com/Miodec/deej
The following libraries are used:
TaskScheduler - Cooperative multitasking for Arduino
FastLED - FastLED library for colored LED animation on Arduino
The code on GitHub is only a snapshot. The development takes place on a self hosted git instance, thus you will not find a proper git history here.
This code has been developed using vscode with the PlatformIO plugin and tested with an Arduino Nano-V3 328PB Module.
With the PlatformIO plugin the installation should be straight forward.
In the src/main.cpp you can modify min and max brightness of the LEDs by changing the values of MAXBRIGHTNESS and MINBRIGHTNESS.
The colors of the app sliders are set in the setup() function. The values are provided in the HSV format, but keep in mind, that FastLED maps the HSV color values to the 0-255 number range. So a hue of 300 should be provided as 212.
