Hands-On Internet of Things with MQTT

Develop a variety of projects and connect them to microcontrollers and web servers using the lightweight messaging protocol MQTTKey FeaturesLeverage the power of MQTT to build a pet food dispenser e-ink to-do list and a productivity cubeLearn about technologies like laser cutting 3D printing and PCB production for building robust prototypesExplore practical uses cases to gain an in-depth understanding of MQTTBook DescriptionMQ 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.What you will learnExplore MQTT programming with ArduinoDiscover how to make your prototypes talk to each otherSend MQTT messages from your smartphone to your prototypesDiscover how you can make websites interact with your prototypesLearn about MQTT servers libraries and appsExplore tools such as laser cutting and 3D printing in order to build robust prototype casesWho this book is forIf you are an IoT developer or enthusiast who wants to start building IoT prototypes using MQTT this book is for you. Basic knowledge of programming with Arduino will be useful. About the Author Tim Pulver is a Berlin-based freelance interaction designer and developer. In his work he combines his physical prototyping experience and knowledge of interface design with modern technologies such as 3D printing laser cutting web technologies and machine learning to create unique interactive experiences. In recent years he has worked on interactive data visualizations web-based audiovisual experiences musical interfaces and cables― an innovative browser-based visual programming language that enables the creation of interactive audiovisual prototypes without writing any code. He holds a Bachelor of Arts degree in interface design from the University of Applied Sciences in Potsdam Germany.
