Another (Arduino) Audio Spectrum Analyzer

Posted January 6, 2014 by Chris

"My last project is an audio spectrum analyzer. The work has been done using a MSGEQ7 integrated. The result is shown using an 2X16 LCD display. The bars are built using defined characters.
The chip only gives 7 info of frequency. I’ve arrived until the 16 bar interpolating values based in the 7 given."
