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.

Building a Smart Productivity Cube, Part 1

In the previous chapters, we built a smart pet food dispenser and a smart e-ink to-do list. In this chapter, we are going to build a smart productivity cube. By using mechanical tilt switches, we will be able to sense which side the cube is standing on. We will then assign that position to an activity (for example, learn MQTT) and log how long we pursue this activity.

After following along with this chapter, you will know how to build your own orientation sensor using tilt switches. This chapter serves as the basis for the next chapter, Chapter 8Building a Smart Productivity Cube, Part 2, where we will learn how to enhance your smart productivity cube with MQTT and how to display its information on your smartphone using Android and iOS apps. 

In order to facilitate the learning process, the chapter is divided into the following...
