Preface

As soon as the announcement for the Raspberry Pi Pico was made by the Raspberry Pi Foundation in January 2021, we were excited by the new possibilities that the USD 4 developer board would open for hobbyists, generalists, citizen scientists, professionals, scientists, teachers, and students around the world. Available in various forms, the powerful yet inexpensive microcontroller can indeed stand on its own and work with other tools to help people develop very powerful and elegant solutions. We expect that just like the prior generations of products from the Raspberry Pi Foundation, the Raspberry Pi Pico is going to create another revolution in the realms of technology, education, entertainment, and other societal endeavors.

Based on our experience in penning books and articles on the Raspberry Pi Single-Board Computers (SBCs), we designed this book to dive into new and repeat projects so we may cater to the varying needs of the target audiences, such as students, teachers, engineers, scientists, artists, and tech enthusiasts who want to develop embedded systems that drive cost-effective automation, IoT, robotics, medical devices, and art projects.

We have tried to retain variety in the projects, while also introducing different sensors, programming, interfaces, and other factors sufficient to pave the way for both beginners and advanced readers to ideate and implement projects based on the Raspberry Pi Pico.
