Description

A device to switch audio devices (e.g. headset < - > speakers) in Windows, change the volume and mute the microphone.

The AudioController is based on a Arduino (wemos D1 mini) which communicates with a Windows Powershell script via serial connection. In addition to the CH340 driver, no other drivers are necessary. No native USB is used.

All scripts and other ressources can be found in this project.
