![]() Node-RED: Lecture 5 – The Node-RED programming model In this lecture, you’ll take a more detailed look at Node-RED’s programming model and some of its key concepts and explore the details of the message flow model that underlies Node-RED. Node-RED: Lecture 4 – A tour of the core nodes This lecture will take a look at the core set of nodes that Node-RED installs by default and then show you the extended set of nodes that the cloud-based Node-RED service – FRED – supports. Then you’ll briefly look at other ways to get messages into and out of your flows using protocols such as TCP, UDP and websockets. You’ll start off with a series of examples based around the popular MQTT protocol that shows how to wire together a set of basic but very useful message processing nodes. Node-RED: Lecture 3 – Basic nodes and flows In this lecture you will get to see a few of the more commonly used nodes and build on some of the things you learnt in previous lectures. ![]() You’ll learn how to create simple flows, use debug nodes to track messages through the flows and how to use the function node to write simple JavaScript code that tailors the node to your specific needs. Node-RED: Le cture 2 – Building your first flows This lecture will introduce you to the Node-RED visual tool and get you started building your first flow. We’ll also discuss the history of Node-RED and its origins to give you an idea of what Node-RED is good for and of what types of tasks are best left to a more traditional programming language and environments. ![]() ![]() Node-RED: Lecture 1 – A brief introduction to Node-RED This lecture will introduce you to some examples of Node-RED, both to give you a sense of its capabilities and to introduce its basic concepts. Each lecture consists of a series of hands-on examples that take you from basic to intermediate Node-RED programming in easy to follow steps. Starting from the very basics, it introduces you to how Node-RED works and how to get the most out of its built in nodes. The node red guide is a series of lectures designed to get you started with Node-RED.
