I made a super responsive remote control volume knob using Arduino and ESP-Now.

Its super satisfying to have an actual weighted and precise volume knob, rather than buttons on a remote control. Link to solid model files and Aduino code: https://etischer.com/arduino/remote_v... I first soldered 3 wires to the volume knob in my DAC / Preamp, and connected them to an Arduino using a pair of OptoIsolators. A second Arduino reads a cnc rotaray encoder, and sends that signal to the first Arduino using a direct wifi connection called ESP-Now. SMSL D-6s DAC https://www.amazon.com/S-M-S-L-ES9039...
