Step 1: The Schematic & Audio Solution
I needed to be able to control each of the 8 LED strips (each strip is 10 feet long) individually. Controlling each LED in the strip individually would have been nice but was not required for this project.
After a bit of research, I landed on the folks over at usledsupply.com. Their service was great, they answered all of my questions even the dumb ones in a timely manner. They also did a custom wiring schematic based on my requirements and pre-cut the LED strips to the lengths I needed.
The project also needed sound for the Breathalyzer feature as well as some of the other effects, the Adafruit WaveShield fit the bill for this. Line level audio comes out of the WaveShield and goes into an existing whole house audio sound system (the Nuvo Grand Concerto). It was a 70ft run to the Grand Concerto audio system and unfortunately line level audio picks up noise very quickly on long runs so audio baluns over CAT5 were used to eliminate the noise.
For the Graphic Equalizer (VU Meter) feature, line level audio goes out from the Grand Concerto audio system into an analog input pin on the Arduino Mega.
usledsupply.com had an off the shelf LED controller for controlling the colors, dimming, flashing, etc. So I wanted to be able to use this controller along with the Arduino Mega for the lightning simulator/breathalyzer/graphic equalizer functions. The way this works is you simply turn on the controller you want and turn the other one off.

i have been done that road
I am really tempted to build something similar to this, I was just wondering how you got the audio inputs (You had the waveshield for the output) and also how you did the spectrum analyzing.
Thanks!
Keep up
congrats.
