Take a look here.http://amblone.com/index.phpThe colors are extracted from an pc with a Visual C++ 2008 program.An arduino is used for the LED'sSources etc availableI've not tried it, but it's on my todo list (long,long list )
I was hoping to leave a computer out of the equation so hopefully I can get something working with just the arduino.
I am not entirely sure, but you may be able, if you have an LED backlit TV, take some voltage/current readings off the backlight circuits and use them to help with making the outputs match the intensity of the screen.
