Look at all these shields!!! Laying them out on my desk for organization was great. I'm learning to use arduino and these are helping. You can do all sorts of little experiments with them, sometimes with multiple ones at a time. There's an initial period of matching all the shields to their picture and description but it was all there in the end, get yourself a parts-box or organizer though, so you don't have to play the matching game every time. Great overall gadget pack, get it and you won't need another shield for a long time.
