It also gives me the ability to mute when the phone conference tool is not focused (as i will see in the PC tools sections).

So you can easily create USB HID devices with this board. This projects uses this ability to emulate a keyboard, which only sends the pre-programmed keystroke, which is used to mute/unmute (I am using CTRL+F12). Simple wiring. Don't forget the LED's series resistor! There is no back-channel, so initially the mute-button assumes the system is unmuted. In case the mute-button assumes the system is muted, an LED is switched on. The LED is switched off otherwise. In muted state, you can keep the button pu...
