Arduino powered Jack ‘O Lantern, Jon writes-
The Ladyada/Adafruit tutorials are great. I have gone from never having picked up a soldering iron to this project over the course of a couple months of experimenting. This uses an LED array soldered onto a piece of project board from radio shack and has its own 12v power source made from a dc adapter from an old broken external hard drive. I’m using an Adafruit WAVE shield for the audio and a RadioShack powered speaker.
The lantern will randomly cycle through colors until the motion detector is triggered, then it will randomly speak one of a number of audio clips I recorded, the will go back and cycle through the colors.
