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.

For each node, you’ll see a brief overview of its functionality and an indication of which example in this lecture series uses the node, so you can look in more detail at how to work with the node.… Read the rest

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 processing nodes.… Read the rest

Node-RED: Lecture 2 – Building your first flows

This lecture will introduce you to the Node-RED visual tool and get you started building your first flow. 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.… Read the rest

Node-RED: Lecture 1 – A brief introduction to Node-RED

Node-RED is a powerful tool for building Internet of Things (IoT) applications with a focus on simplifying the ‘wiring together’ of code blocks to carry out tasks. It uses a visual programming approach that allows developers to connect predefined code blocks, known as ‘nodes’, together to perform a task. The connected nodes, usually a combination of input nodes, processing nodes and output nodes, when wired together, make up a ‘flows’.… Read the rest
