The LilyPad Arduino is a set of sewable electronic components that let you build your own soft, interactive fashion. To get started, snag this LilyPad starter kit that I put together. Or, browse through the LilyPad category on SparkFun to get just the pieces you need. Work through the tutorials here to learn how to build all sorts of soft interactive stuff...perhaps fortune telling shirts, jackets that sing when you're squeezed or turn signal equipped cycling wear? Enjoy!
