Turn A Raspberry Pi Into A Wireless FM Microphone

Wireless microphones give you the freedom to move around while amplifying your voice, but they can be incredibly expensive. With a Raspberry Pi, a few cheap components and a radio, you can create one for a lot less.

This could be useful for giving lectures or presentations where it might be hard to hear you and there isn’t a professional PA system. You could also use it in a van or other large vehicle to communicate over the car’s speakers. You can find the full component list, necessary code, and step-by-step instructions at the link below.
