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
David

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.
