In the first chapter of this book, we looked at how to configure our Raspberry Pi Zero board so we can use it in later chapters. We looked at what components were needed for the Pi, and how to install Raspbian so we can run the software on our board.

We also installed a web server, which we will be using in some projects of the book. In the following chapter, we are going to dive into how to connect devices to your Raspberry Pi and Arduino boards. We'll also look at the various things we can connect to the Raspberry Pi using GPIO.
