I'm looking to bild an outdoor project that involves programable/contolable faiding/blinking multicolored water resistant individuality or group controlled LEDs that would be installed in and around trees to give a firefly or "fairy" aperance. I know I'm going to need 40-60 feet of wire to cover the area I want. if the great arduino forum could help me with a parts list, programing ideas, wiring ideas, and/or related topic links, it would be much apriciated.
You might want to get a strip of these: The Magic of NeoPixels | Adafruit NeoPixel Überguide | Adafruit Learning System
You can separate the strip into individual RGB LEDs and encapsulate them in silicone caulk.
