Node-RED: Lecture 5 – The Node-RED programming model

As you’ve seen in previous lectures, Node-RED uses a visual flow-based programming paradigm[1]. This is not unique to Node-RED. Similar approaches have been used in many other domains such as music and multimedia (Max MSP), toys (Lego Mindstorms), enterprise application integration and industrial automation (LabVIEW).

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 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 Continue reading “Node-RED: Lecture 3 – Basic nodes and flows”
