Key FeaturesDiscover how you can automate the IoT without writing huge blocks of code
Build and work with IoT projects with little to no coding knowledge
Learn how to wire together flows using a browser-based visual editorBook DescriptionNode-RED is a free and open-source flow-based programming tool used for handling IoT data that allows programmers of any level to interconnect physical I/O, cloud-based systems, databases, and APIs for building web applications without coding.Practical Node-RED Programming is a comprehensive introduction for anyone looking to get up to speed with the Node-RED ecosystem in no time. Complete with hands-on tutorials, projects, and self-assessment questions, this easy-to-follow guide will help you to become well-versed with the foundations of Node-RED. You'll learn how to use Node-RED to handle IoT data and build web applications without having to write complex code. You’ll explore various techniques and find out how to make sample flows as you cover web development, IoT development, and cloud service connections and finally build useful real-world applications.By the end of this book, you’ll have learned how to use Node-RED to develop a real-world application from scratch, which can then be implemented in your business.What you will learnUnderstand the history of Node-RED and why you need to learn a flow-based programming tool
