Change the volume of any app on your PC with the turn of a knob

Arduino TeamJuly 7th, 2020

Overall computer volume control is important, but what if you want to get more granular, adjusting sound from various applications individually? Rather than going through a series of menus and on-screen sliders, Ruben Henares’ Maxmix lets you do this on the fly.

Based on an Arduino Nano, the simple yet stylish knob takes input from an encoder and button to select a program and rotating it turns the volume up and down.

There’s also a desktop application that needs to be installed, while a small OLED screen on the Maxmix that shows which application is running. There’s even an optional LED ring for extra lighting effects.

All the electronics are housed inside a nicely designed 3D-printed enclosure. You can find files for the case along with build instructions on Henares’ site.
