Sounds sensors allow you to create circuits and machines that respond to sound.  In this tuorial, you’ll learn how they work as well as how to build and code a circuit that uses one.  

Find out how a sound sensor works in this video tutorial. 

Build a simple sound sensor circuit with this diagram, and then you’ll be able to create machines that hear and respond to sounds.

Code your sound sensor with this code, and then use the serial monitor to see when it is hearing a sound.
