I am still receiving many requests to post an Arduino Sound Machine project. I think now is the right time to prepare a primer for beginners. First, keep your expectations low, as I don’t have ...

Arduino enthusiasts and beginners may be interested in a new add-on board designed for the Arduino Uno microcontroller featuring 10 of the most popular modules and sensors for the Arduino platform.

This module shows how to use the Adafruit electret microphone to measure frequency. A companion module explores loudness. The presentation material and the code can be downloaded at SoundPitch.

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 ...

Inside you’ll find an Arduino board, microphone, and an 8×8 RGB module. The front cover of the project box diffuses the light using a sheet of tracing paper on a frame of foam board.
