Get started with the LilyPad Arduino! It's a sewable microcontroller that lets you embed lights, sounds, sensors, and much more into your wearables, perfect for clothing and accessories. In this Make Magazine video tutorial, you'll see how to attach the LilyPad and power supply to each other, and upload a basic program that blinks an LED.
The LilyPad Arduino is a microcontroller board designed for wearables and e-textiles. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread. The board is based on the ATmega168V (the low-power version of the ATmega168) (datasheet). The LilyPad Arduino was designed and developed by Leah Buechley and SparkFun Electronics.
