DIY Spectrum Analyser with a Dot-matrix Display

 Arduino enthusiast and writer John Boxall has just completed another chapter in his series of tutorials - and in the latest edition is a great project that uses our Freetronics dot-matrix display board as an output device for the MSGEQ7 spectrum analyzer IC. The project is quite simple, and using a few parts a full seven-band stereo spectrum analyzer can be possible. Even with one display unit the results are effective, for example:

The tutorial includes a full explanation of the equalizer IC and Arduino sketches, so anyone can have a go. So grab a DMD and get started from here. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

For the uninitiated, the Freetronics Dot Matrix Displays are simple to use, yet very bright for indoor and outdoor situations. Available in various colours, the 32 x 16 LED matrix can display text and graphics quite easily - and can be daisy-chained together for extended displays.
