🎛️ Potentiometer Volume Knob
ArduinoHIDC++3D PrintingDIYPython
Classic "I had an itch" project. I wanted a physical volume knob for my laptop while working. Rather than buying one, I wired a potentiometer to an Arduino Uno R3 and 3D printed a small enclosure for it.
The whole thing took an afternoon and cost about €11 in parts. These are my favourite kind of projects: small, fast, solves a real problem.
