Based on the "oversized MEDIA CONTROL volume knob" from Josef Prusa: https://blog.prusaprinters.org/3d-print-an-oversized-media-control-volume-knob-arduino-basics/

But this version works with an ESP32 and over Bluetooth.

Connect DT from the rotary encoder to D13, CLK to D14 and SW to D12, also connect GND from the encoder to GND from ESP and + to VIN.

The Arduino library can be downloaded on github: https://github.com/T-vK/ESP32-BLE-Keyboard
My arduino sketch can be downloaded here: https://duke24.badberg-online.de/s/ESP32Sketch-mediacontroller

You also need the ESP32Encoder library, wich can be installed directly in the IDE.

The file "version2oberteil.stl" should be printed upside down with supports. The file "gerndelt-Play-Pause.stl" should also be printed upside down but needs no support.
