Sound Level

Last Updated: 7/26/18

Teaching Standard:

By attaching a microphone to an Arduino, you open up a new world of things to try.

•        Measure the sound intensity - Turn on a red light if it gets too loud!

•        Give sound commands: two claps turns on a light, one clap turns it off (anyone remember “The Clapper”?)

•        Measure and display the frequency content of music

•        Make a tuner for a guitar

This module shows how to use the Adafruit electret microphone to measure loudness. A companion module explores frequency.
