"The Internet of Things" is the new buzzphrase, but what is it? A toaster that texts? The fitness band on your wrist? The camera in an infant's room? Sure, it's all of those things -- and your cell phone, too! -- that sense your world and report back. The great thing is that it is actually not hard or expensive to make a sensing, communicating object yourself. Doing so can be rewarding, fun, and even useful. This book teaches the basics of building sensors and communicating objects through a series of practical, demonstrative, and fun activities.
This is a good simplification of ~10 Arduino projects. From the cover, it wasn't clear that this is Arduino projects. I think this probably requires some decent knowledge of computers (and programming/command line interactions) from one family member. It is written at a level that simplifies lots of the details that bogs down other books. The IFTTT section was some good insight. Others (such as the first project to turn on an LED) are fairly basic if the family has much experience with Arduinos - maybe it gets everyone in the family up to speed. Overall, a good family project book (if you want all the projects to be Arduino - from the cover I expected not just Arduino projects)
