Hi All,
I need to use 30 IR sensors (PIR) for an interactive installation. This sensors are triggering a punctual light over some objects that people could touch.
I also need to create a led system, like a disc, imagine something similar to a Tron light disc and the color of the lights are also changing. What should I search for this? I know exist some lines of rgb-leds, but how can I control de electricity and also the color of the leds? What is the better way to do this?
I hope it is clear the questions,
Thanks a lot for the help


What is your question about the PIR sensors? As for the leds, do individual leds need to be different colors? If so, use something like this: http://www.sparkfun.com/products/10312 If not, use a similar one but thats not addressable.
