About the book: 2017 / Arduino is a standard microcontroller that has gained wide recognition among engineers, craftsmen and teachers due to its simplicity, low cost and wide variety of expansion boards. Expansion boards that connect to the main Arduino board allow you to access the Internet, control robots and home automation. Simple Arduino-based projects are not difficult to implement. But as you enter territory not covered in introductory tutorials and increase the complexity of your projects, you'll quickly run into the problem of lack of knowledge—the enemy of all programmers. This book is designed as a sequel to the best-selling book Programming Arduino: Getting Started with Sketches. Although this book includes a brief review of the basics from Programming Arduino, it will introduce the reader to more advanced aspects of programming Arduino boards..
