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 video I’ll show you how to attach the LilyPad and power supply to each other, and upload a basic program that blinks an LED. You can use Arduino with Windows, OS X, and Linux. Next time I’ll show some more advanced topics including hooking up a sensor and using it to change the circuit’s behavior.
