Hands-On Internet of Things with MQTT

By: Tim Pulver

Overview of this book

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.

Installing the essential tools and libraries

In this section, we are going to install all of the tools that we will need in the hands-on part of this book: the Arduino IDE to upload code, Arduino MKR WiFi 1010 board drivers, Visual Studio Code to open non-Arduino code files, and Mosquitto, an MQTT server and toolkit for easy prototyping.

We will also set up an account on shiftr.io, a free MQTT web service, which comes with a useful dashboard.

Additional libraries, which are only needed in one of the hands-on projects, will be set up in that specific chapter.

Installing Arduino

The first application that we are going to install is the Arduino integrated development environment (IDE). It will be used in all of the hands-on...
