In a first step, Myute is assembled without any PCB. Wires are soldered between the Seeeduino Xiao, the KY-040 and the WS2812B RGB LED. The base and wheel are both designed with FreeCAD and printed with PETG.

Arduino is used to read the KY-040 by including the following lib: https://github.com/dmachard/KY040-rotary

A C++ Application is developed with Visual Studio to let any Windows Compute interact with Myute.

The following features are implemented:

• right / left turns decrease / increase the volume
• a button press either mutes or unmutes the microphone
• the RGB LED indicates the current mute status

The C++ Application is scanning COM-Ports at startup. If avaiable, it automatically connects to the Myute Hardware.
