Chapter 8. On the Wi-fly

In this chapter, we will have a look at yet another new Arduino compatible board called the Particle Core. The big feature with this board is that it includes Wi-Fi connectivity in a very small form factor.

One of the first consumer products including Wi-Fi technology which was not a personal computer was weirdly a bathroom scale. Today, we find stereos, robot vacuum cleaners, light bulbs, and even refrigerators that include Wi-Fi technology. The reason for this is of course to connect these products to the Internet.
