Arduino Uno running a MSGEQ7 and a LCD

I Have an Arduino Uno running a MSGEQ7 and a LCD.  It is sampling each frequency twice for 14 samples each channel.  The MSGEQ7 control pins are connected to D2 and D3.


Here is a video of it working.



Here it is simulating an analog meter.


I added a 4052 analog mux to the MSGEQ7's to get 28 frequencies per channel.


This is the same setup with a sweep generator.


Here is a video with a stereo analog meter.
