In this chapter, we presented most of the projects that will be discussed in this book, together with circuit diagrams that show how to connect our hardware components. We also introduced development using C# for Raspberry Pi and presented the basic project structure. Several Clayster libraries were also introduced that help us with common programming tasks such as communication, interoperability, scripting, event logging, interfacing GPIO, and data persistence.

In the next chapter, we will introduce our first communication protocol for the IoT: The Hypertext Transfer Protocol (HTTP).
