Hi there - thanks for sharing the info on this project!
I'm looking to do exactly the same thing and was wondering if you have a schematic of the finished working version. I'm also a newbie & don't recognise some of the components ont he board.
To answer some of the earlier questions about why I need this - I'm in a project called temp0rary ( temp0rary.com ) and we have a live VJ as part of the band. He's running his computer pretty hard with all the clips, so what we need to do is take the VGA signal from the projected visuals, do some very rough analysis of the R/G/B values, and then have LED lighting on stage that sort of follows what's going on with the visuals (i.e, if visuals are mostly red, the performers light up red too, dark is dark, bright is bright, nothing more than that really...)
Because we already have a lot of kit, and the laptops on stage are already dangerously close to maxed out, it makes more sense to split the VGA, analyse is in a quick & dirty fashion with an Arduino, and use that to squirt out RGB values to control the LEDs.
If anyone has any other info about controlling LED lights like these ones, please let me know!:
