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 intermediate, soft circuit, video tutorial, you'll see how to make a light-up patch that can be used on your backpack for fun and bike safety. Get the details.
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.
