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

Key Features

• 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

Book Description

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.

What you will learn

• 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

Who this book is for

If you are an IoT developer or enthusiast who wants to start building IoT prototypes using MQTT, this book is for you. Basic knowledge of programming with Arduino will be useful.
