Set app volumes with real sliders! Arduino project to build hardware
...The sliders are connected to 5 (or as many as you like) analog pins on an Arduino Nano/Uno board. They're powered from the board's 5V output (see schematic). The board connects via a USB cable to the PC. The code running on the Arduino board is a C program constantly writing current slider values over its serial interface. The PC runs a lightweight Go client in the background. This client reads the serial stream and adjusts app volumes according to the given configuration file.
