Build a simple physical mute button for video conferencing on Zoom using a Raspberry Pi Pico

Miguel Grinberg has written a really great beginners’ tutorial to the world of USB HID using the Raspberry Pi Pico. For this project, he adds a Pico to a breadboard then hooks up a simple momentary button. Pressing the button sends a keypress to Zoom which mutes and unmutes the software. The software is CircuitPython, which has USB_HID already available and it can easily be expanded to send other commands, like turning your video off, for example. You can read Miguel’s tutorial here.
