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.
