Ikea Table Audio Visualizer

This is the circuit embedded in the table.  The Arduino Uno feels a bit overpowered for this, but it was the quickest way to get both 3.3V and 5V power.  The second ground is important, as the microphone works best when using a dedicated ground connection.

I built a small board to hold the through-hole components and MSGEQ7. 

This is the best result I could get with the initial construction.  The response is very uneven and I cannot get the higher frequencies to register at all.
