SparkFun LilyTwinkle

SparkFun LilyTwinkle is a tiny LilyPad board designed to add some twinkle to a project. The LilyTwinkle is as small as some of the LilyPad sensors but has an ATtiny microcontroller. Sew on four LEDs and connect a battery, and the LEDs will twinkle-fade. SparkFun LilyTwinkle is a quick and easy way to add twinkling lights to a project without any programming or a bulky mainboard.
