View Full Version : Home Brew Music Visualization White Board - Arduino - GE Color Effects Lights

This is kind of xmas lights related in that I'm using 4 strings of GE Color Effects (25 Count) lights (http://www.amazon.com/Color-Effects-G-35-Light-Lights/dp/B0085Y0QSE/ref=pd_sim_sbs_hg_6) controlled by an Arduino UNO R3 and the spectrum analyzer shield (https://www.sparkfun.com/products/10306) from sparkfun.com (https://www.sparkfun.com).

Arduino based LED music visualization project. This project is something I've been wanting to do for a while now. It seemed like a good follow up to my Arduino/Vixen Christmas lights controller (http://doityourselfchristmas.com/forums/showthread.php?23956-Home-Brew-Lighting-System-Arduino-Mega-SainSmart-16-Channel-Relay-Board), videos for that project can be found here (http://www.youtube.com/playlist?list=PLp21wF8e4XnjNSQHJcnvNSDdb1wsPOfHi). If you have seen one of the many LED music table projects on YouTube then know what I'm doing.

For a quick, and fairly straight forward, project this one has been one of my more expensive projects. Mainly due to the light strings.

Here is the YouTube playlist link for the project videos. (http://www.youtube.com/playlist?list=PLp21wF8e4Xng5j6fdSD9A1c0W8lONnVxk)

Once I get most of the effects code finished I'm thinking about also being able to control this project from Vixen as an extra bonus.

Wow! That brings back fond memories when I built the "Musette Color Organ" by Don Lancaster as published in Popular Electronics July 1966. It was a 5 channel analog device. Still have that issue.

Holy cow, that was 4 years before I was born. :) Although my dad and I did spend a lot of time going through PE mags when I was young.

I'm also curious to see how you will deal with the channel information so that each filter has a full brightness level for a given song, while playing the music. Of course it depends on the energy content per filter of a given song. That was a problem I had with the Musette and it made some channels of the display look dim and "whimpy" for many songs. If a sequencer, like Vixen, HLS,..., is used then the user can set the brightness level for each filter.
