# Arduino and MSGEQ7: Simple Spec Analyzer


Putting music signal into the Analog Input of an Arduino can be pretty boring. That is, unless you use a totally awesome chip like the MSGEQ7. This  [simple Spectrum Analyzer driven with an Arduino](/msgeq7-simple-spectrum-analyzer.html "MSGEQ7 Simple Spectrum Analyzer") only takes a handful of parts.  I used these [incredibly awesome protoboards](http://www.adafruit.com/product/1148 "Adafruit Awesome Proto Boards") from [Adafruit](http://www.adafruit.com "Adafruit Industries") for the first time.   The protoboard alone gives a fit and finish even before it starts!
