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.

Connecting the e-paper module/running the example

The next step is to connect the e-paper display to the Arduino MKR WiFi 1010. By looking at the connectors of the e-paper panel and comparing it to the available ports of the Arduino MKR WiFi 1010, we will see that the following port names match:

  • GND
  • VCC (3.3V)

Ground (GND) and power (VCC) are needed for every module, so no surprises here. For the other ports, we have to find out how to make it work.

My first step here would be to run a Google Search to find out if somebody posted a tutorial for the module we want to use with our microcontroller. This would mean searching for the Arduino MKR WiFi 1010 Waveshare 4.2 e-paper module.

I could not find any results (probably because Arduino MKR WiFi 1010 was very new when writing the book). To find out which ports to use, the best bet is to search for...
