Update Jan. 23, 2021: Looks like the Joystick circuit has failed as it no longer toggles the Mute function. Well, I wasn’t too happy with the initial wiring job so this may be an opportunity to update that.
A while ago I developed an interest in Arduino microcontrollers, and this is my first ‘actual’ project.
It’s a box that sits adjacent to the keyboard and lets me control the output volume of various applications before they reach the speakers or headphones. Also the input sensitivity of a microphone.
Most of the magic is achieved through Deej, an application that sits in your task bar and controls the Arduino inside the box.
For more detail on my build, check out the Instructable.
