4x sliders to controll various volume levels on Windows. Uses Arduino Pro micro to read analog values from slider and sends them to computer running Deej, Arduino also dimms 8mm PL9823 leds (ws2812b leds also work) according to the volume level.

Does not need any skrews of glue. Only antiside pad must be melted with soldering iron (from small knobs to main body)

Print materials Main body - Extrudr PLA NX-2 Black Top plate - Fillamentum PLA Extrafill Vertigo Grey Antislide - Recreus Filaflex 60A Pro Black

For best looks print top plate on glass plate to get it super smooth and reflective

Parts used 1x USB C Arduino nano 2x Slider potentiometers 4x 8mm PL9823 leds 4x decorative 8mm led housing

Arduino code provided ain't the best or most efficient but it works for me, if you use my code make sure to set "noise_reduction: low" in deej config.yaml

Currently left slider has red color and is intented to be used as main volume controll, so it dimms other leds accordingly. I use other channels to for google(green), games(yellow) and discord(blue)
