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.

Using 3D printing to build custom cases

In the previous sections of this chapter, you learned how to build a case for your prototype using household boxes and laser cutting technology. In this section, you will learn about a third option that you can use to produce nice-looking cases for your prototype, 3D printing:

3D printing is a technology that allows you to create a three-dimensional physical object from a digital file. It works using additive processes—that means processes in which an object is created by adding successive layers of materials (as opposed to removing materials) until the object is completed. The greatest advantage of using this technology is that it allows you to produce complex shapes using less material and more cost-effectively than when applying other manufacturing methods...
