Run an audio signal through it and you have an instant audio spectrum analyzer! This is a simple spectrum analyzer based on an Arduino. Each of the 5 LEDs represent a single section of the chip’s 7 sections of audio spectrum. MSGEQ7 on Adafruit Protoboard Electronics If you want to replicate this setup, here is the hardware you’ll need to get.

That is, unless you use a totally awesome chip like the MSGEQ7. This simple Spectrum Analyzer driven with an Arduino only takes a handful of parts. I used these incredibly awesome protoboards from Adafruit for the first time. The protoboard alone gives a fit and finish even before it starts!
