The LilyTwinkle is a tiny little LilyPad board designed to add some twinkle to your project. Even though it's as small as some of the LilyPad sensors, this board actually has an ATtiny microcontroller on it so it's actually pretty smart! Simply sew on 4 LEDs and connect a battery and the LEDs will twinkle-fade (a lot like fireflies... or lightning bugs, if that's what you call them). LilyTwinkle is a quick and easy way to add twinkling lights to a project without any programming or a bulky Main Board.
