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.

In this chapter, we learned how to build an orientation sensor using tilt switches from scratch and saw how to improve it step by step. We discussed how to hide the complexity of our project by building a cube around it to make it presentable.

In the next chapter, we will build upon this by adding MQTT into the mix. The cube will be enhanced to broadcast the associated activity along with the stopped time, for example, Watching TV: 123 minutes.

We will also have a look at how to make use of MQTT clients for Android and iOS to display the data published by the cube.
