Ready to add audio to your next project? The SparkFun Electret Microphone Breakout couples an Electret microphone (100Hz - 10kHz) with a 60x mic preamplifier to amplify the sounds of voice, claps, door knocks or any sounds loud enough to be picked up by a microcontroller’s analog to digital converter.

All in one tiny package!

The Electret Mic Breakout translates amplitude (not volume) by capturing sound waves between two conducting plates (one a vibrating diaphragm and the other fixed) in the microphone and converting them into electrical waves. These electrical signals are then amplified and picked up by your microcontroller's ADC. In this tutorial, we will present two different projects to get you up and running with your next sound reactive project in a snap or a clap.
