The product appears to no longer be supported and the libraries that are available are all out of date. Since I had managed to update them and add some functionality, I wanted to share this with ...

This project presents the design, implementation, and evaluation of an Arduino-based mini sound level meter. The device provides accurate dBA measurements reflecting the sensitivity of human hearing ...

The Arduino is a real jack-of-all-trades. You can use this inexpensive microcontroller board for all kinds of things thanks to the expansion connectors for which countless 'shields' are available. In ...

A sound sensor is a simple, easy-to-use, and low-cost device that is used to detect sound waves traveling through the air. Not only this but it can also measure its intensity and most importantly it ...

[Chris] wrote us to share a neat technique he has been using to program the Arduinos he uses in his projects. He likes to build bare bones Arduino clones rather than sacrifice full dev boards, and ...

Chirp and Arduino announced the first official integration of data-over-sound on Arduino’s range of boards. The integration allows Arduino-powered projects to send and receive data wirelessly through ...
