A Tutorial Introduction to IoT Design and Prototyping with Examples (Second Edition)

The dramatic drop in price of computing hardware, coupled with the recent breakthroughs in embedded systems design that enabled the integration of high-level software and low-level electronics, have created a paradigm shift in embedded systems. This has led to the development of different varieties of user-friendly hardware development platforms for Internet of Things (IoT) prototyping. The ubiquity of such prototyping platforms has undoubtedly contributed to the significant growth of the IoT, which is already seeping into all areas of human endeavor, including transportation, logistics, agriculture and healthcare. Building IoT projects that can be controlled over the Internet can be challenging, especially for beginners. This chapter discusses the design and development of prototypes for IoT applications, with a focus on the Arduino and Raspberry Pi platforms. The aim is to provide insightful information on best practices for designing and prototyping IoT projects, as well as to serve as step-by-step guidelines for beginners.
