About this project

All my meetings are now virtual, and I found it irritating fumbling to unmute myself to speak.

So I created my own button to toggle the mute. My code is specifically for MS Teams, because that's what we use at work.

I wanted to use a digispark, because they're small and cheap, but those appear to be unavailable. So my second choice was an Arduino Micro which has native USB support to emulate a keyboard.

AutoHotKey Macro

1) Install AutoHotkey
2) Create a text file "teams_mute.ahk" with contents below
3) Open the file with autohotkey
4) Ctrl-Alt-M should send mute command to teams window, then switch back to the active window
5) Optional: add to startup applications:
a) Window-R and type: shell:startup
b) It will bring up the folder with your startup apps
c) create a shortcut to the script and place it here
