The basis for this project is the Keyboard Arduino library. Within Teams the microphone can be muted using the + + keyboard shortcut and the switch I made just emulates these keypresses. This is a quick build and is entirely based around keyboard shortcuts in Windows. Once I had the correct components it probably took less than 15 minutes to have something that works. This constant struggle to remember to click one single button when I want to speak led to this, making a physical switch to mute and unmute myself when using Microsoft Teams.Īs a bonus, this was one of those rare projects where you get something really useful with very little effort. It takes only four simple words halfway through a lengthy explanation to remind us we learn very, very slowly… “You are on mute”. After almost a year you would think that we all would have this under control. While working from home I, like millions of others, am stuck in constant conference calls.
