- Some technologies associated with IoT are smart homes, smart cars, and IIoT/Industry 4.0.
- Voice user interfaces such as Alexa and Siri are used more and more to control internet-connected devices.
- It does not make sense to make every device smart. The more features a device has, the more likely it is for problems to appear. Would you rather have a traditional vacuum cleaner that works 99% of the time, or a vacuum cleaner that only works when a wireless network connection is available but that shows its status in an app?
- Prototypes are used to find out if your idea works or not. They can be developed in a quick and dirty way and are all about getting the desired result fast.
- No! The beautiful thing about prototyping is that you don't need to be an expert in every area—especially in the Arduino community, where you will find code snippets and diagrams for most common sensors and actuators. Combining example snippets and adding a little bit of logic to the code might do the job for a first version.

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.
