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. I guess most of you are familiar with Wi-Fi technology these days as Wi-Fi has become a standard for wireless communication in almost all personal computers and smart phones, and in recent years we can even find Wi-Fi technology in many consumer electronics. 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.

Even though I am not that old, I still remember a time when anything connected to the Internet needed a cable, but fortunately those days are long gone. Wi-Fi technology is still older than one might...
