The product appears to no longer be supported and the libraries that are available are all out of date.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 ...

It is, of course, possible to realize such a circuit entirely using only discrete components, but in this article we will show you how you could build one using an Arduino and a multipurpose shield.

Noise pollution has really started to gain importance due to high population density. A normal human ear could hear sound levels from 0dB to 140dB in which sound levels from 120dB to 140dB are ...

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 ...

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 ...

Arduino enthusiasts who are looking to add sound to their projects may be particularly interested in a new generation of Arduino sound card created by electronics developer Masih Vahida. This ...

Programmer Mike Tsao has devised a clever method to program an Arduino board using sound. Programmer Mike Tsao has devised a clever method to program an Arduino board using sound. is executive editor ...

Chirp and Arduino have 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 ...

Now it is very easy to build your own siren sound alarm, small enough to be carried in a garment pocket. This powerful audio-visual alert device is realized using the renowned Arduino platform. The 9V ...

[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 ...
