The Internet of Things is all about connecting the devices that were previously not connected to the Internet, in order to make them smarter and more controllable. Since the size and cost of electronic devices are dropping exponentially, we can now afford to incorporate them in our daily use, are garden watering systems, home automation/monitoring systems, and so on. The Internet of Things in this way has opened up a whole host of opportunities, the advantages of which are being taken up by hobbyists, startups, and major companies alike. At the heart of the Internet of Things revolution are small micro computers and sensors that allow these devices to connect to the Internet and exchange data between them.
As mentioned before, in this particular chapter we will extend our previous projects by connecting the Raspberry Pi to the Internet, and make additional projects to demonstrate the capability of the Internet of Things.
