Hands-On Internet of Things with MQTT

Develop a variety of projects and connect them to microcontrollers and web servers using the lightweight messaging protocol MQTT

• Leverage the power of MQTT to build a pet food dispenser, e-ink to-do list, and a productivity cube
• Learn about technologies like laser cutting, 3D printing, and PCB production for building robust prototypes
• Explore practical uses cases to gain an in-depth understanding of MQTT

MQ Telemetry Transport (MQTT) is a lightweight messaging protocol for smart devices that can be used to build exciting, highly scalable Internet of Things (IoT) projects.

This book will get you started with a quick introduction to the concepts of IoT and MQTT and explain how the latter can help you build your own internet-connected prototypes. As you advance, you'll gain insights into how microcontrollers communicate, and you'll get to grips with the different messaging protocols and techniques involved. Once you are well-versed with the essential concepts, you'll be able to put what you've learned into practice by building three projects from scratch, including an automatic pet food dispenser and a smart e-ink to-do display. You'll also discover how to present your own prototypes professionally. In addition to this, you'll learn how to use technologies from third-party web service providers, along with other rapid prototyping technologies, such as laser cutting, 3D printing, and PCB production.

By the end of this book, you'll have gained hands-on experience in using MQTT to build your own IoT prototypes.

• Explore MQTT programming with Arduino
• Discover how to make your prototypes talk to each other
• Send MQTT messages from your smartphone to your prototypes
• Discover how you can make websites interact with your prototypes
• Learn about MQTT servers, libraries, and apps
• Explore tools such as laser cutting and 3D printing in order to build robust prototype cases
