Chapter 6. Wireless Communication

Alex Beim’s Zygotes (www.tangibleinteraction.com) are lightweight, inflatable rubber balls lit from within by LED lights. The balls change color in reaction to pressure on their surface, and they use ZigBee radios to communicate with a central computer. A network of zygotes at a concert allows the audience to have a direct effect not only on the balls themselves, but also on the music and video projections to which they are networked.

If you’re like most people interested in this area, you’ve been reading through the early chapters thinking, “but what about wireless?” Perhaps you’re so eager that you just skipped straight to this chapter. If you did, go back and read the rest of the book! In particular, if you’re not familiar with serial communication between computers and microcontrollers, you’ll want to read Chapter 2 before reading this chapter. This chapter explains the basics of wireless communication between objects. In it, you’ll learn about two types of wireless communication, and then build some working examples.
