In this chapter, we continued to look at the possibilities to control hardware using the GPIO ports and had a quick look at the additional features of the Pi model B+.

We also looked at some of the issues caused by driving large numbers of electronic devices that require a large amount of power during their operations. We also looked at how these issues can be overcome.

Now that you have completed all the projects in this book, it is time for you to embark on your own projects using the Raspberry Pi and the vast range of devices that can be used with it to create some impressive projects that can interact with the world around you.
