This is hardware volume mixer for windows and linux that lets you control the volume of specific applications.  It follows the deej project located at [https://github.com/omriharel/deej](https://github.com/omriharel/deej)

This is created, in part, to support a class covering soldering and microcontrollers.  The guide for the class is at [https://mkroa.org/deej-guide](https://mkroa.org/deej-guide). Given the focus on the class, this model is meant to be as simple as possible and utilizes a minimal amount of commodity components.

To build this, you will need:

• Arudino Microcontoller with headers
