This book is divided into project chapters. The goal of each project is to create a fully-functional, working prototype electronics device. Some devices are more useful than others (and that’s for you to decide!), but all devices can be extended further beyond the scope of this book, to create even more interesting devices. In this sense, each project is structured to be a foundation for your own device creations.

Each project chapter contains 5 parts:

1. List of required modules, and additional parts if needed
2. Description of the basic functionality of the completed device
3. Block or circuit diagrams to assist you in assembling the device
4. Source code for a compiler to upload to the modules
5. Pictures of the unassembled, and assembled device

The book is organized by modules, so you can quickly navigate to the section containing the modules they have, and build whatever device they wish. As your collection of modules increases, you can turn to other chapters and build differentor more complex devices with time.

As with most technical books, it’s always a good idea to start with an easy project to familiarize yourself with the basics of the modules and programming. The chapters are therefore assigned a star rating, where a 1 star project is generally easier than a 3 or 4 star project. That’s not to say you couldn’t do a 4 star project from the start, but be prepared with plenty of patience!
