For this book, the main component you will need is, of course, a Raspberry Pi Zero board. In the first chapter of the book, I will show you how to completely configure the board, so you can use it for the projects of this book. We will use some basic components at the start, such as sensors, and then move on to using more complex components. For every project, I will of course guide you step-by-step into building the hardware part so that you are not left behind.

On the software side, it is good if you actually have some existing programming skills, especially in JavaScript and in the Node.js framework. However, I will explain all the parts of each software piece of this book; so even if you don't have good programming skills in JavaScript you will be able to follow along.
