This kit has it all. It now includes the new Arduino Uno, the fabled baseplate, and all the sensors you can shake a stick at. This version includes a plastic carrying case to organize all the components. The SparkFun Inventor's Kit for Arduino is a box of goodies to get the very beginner started with programmable electronics. It includes all the bits you need to build 12 basic circuits, no soldering required! On top of that, we've joined forces with Oomlout to offer a small booklet to get you started.
