Motorized Faders Make An Awesome Volume Mixer For Your PC

A DIY hardware project creates a physical volume mixer for Windows using motorized faders and Arduino. The device uses MIDI Mixer software to control per-application volume levels via MIDI commands sent over USB. Built with an Arduino Micro, five motorized faders from Behringer X32 replacements, L293D motor controllers, and six buttons for preset switching. The motorized faders automatically adjust positions when presets are recalled, making it useful for streamers and users managing multiple audio sources.
