Summary
In this chapter, we learned how to connect and interface the GrovePi Shield with the Raspberry Pi, and how to connect the various sensors to it, and use their data to display on external peripherals. We also looked at and understood two examples that can be used easily in real life for useful tasks.
In the next chapter, we will learn about the Internet of Things and how to connect sensors to get the data online and use it effectively. For example, we can extend the intruder detection example and make it such that it e-mails us the photo of the intruder it just took. In this way, we can receive real-time updates from our chosen monitored location. The Internet of Things is a very useful concept and due to the inexpensiveness of the components it takes to get a working system, it is becoming very popular across the globe to make 'dumb' devices 'intelligent'.
