Programming the IoT
In this tutorial we’ll combine two interesting areas, how to build interactive dashboards in Node-RED with use of the new Binance cryptocurrency node that we’ve developed.
The dashboard we are aiming for is shown below – and you can access a realtime, live DEMO of it if you want to see it in action! Continue reading “Tutorial: Advanced dashboards for Node-RED (and cryptocurrency)”
This lecture is a set of links to advanced tutorials we have written. These include:

This is the second tutorial in a series on using the Binance cryptocurrency node we have developed. Take a look at the first tutorial if you haven’t already done so as it introduces you to the basics of the Binance node. This tutorial develops a simple dashboard showing bid and ask prices for symbol BTCUSDT and will look a little like this: Continue reading “Dashboards and graphs for cryptocurrency data using Node-RED: tutorial”
Node-RED’s dashboard nodes provide a comprehensive set of UI components for building basic dashboards suitable for the Internet of Things (IoT) – offering graphs, gauges, basic text as well as sliders and inputs. However, there will always be situations when you need something custom. The template node is the solution and in this tutorial we’ll show you a quick example of using it to create your own UI widget.

This simple tutorial explains how to display multiple lines on a Node-RED chart. We’ll be building on a previous example in our lecture series (Example 7.2 in lecture 7) Continue reading “Tutorial: Node-RED dashboards – multiple lines on a chart”
For our final example of building Dashboards and UIs we’ll use a generic technique we’ve experimented with before. That’s the web service approach that uses a http node to allow us to accept http requests and return web pages. We used this approach in example 1.3 but didn’t explain the details. Continue reading “Lecture 7: Node-Red dashboards (Part 3)”
This second example uses the built in dashboard nodes that come with Node-RED. If you are using FRED, make sure you have selected this node set from the add/remove button in the management panel and that you aren’t Continue reading “Lecture 7: Node-RED dashboard (Part2)”
In this lecture you will take a look at a few techniques to allow you to visualize data passing through flows. We’ll focus on three approaches, the use of a third party dashboard tool, FreeBoard (Part 1), using the default Dashboard UI nodes provided by default in Node-RED (Part 2) and a general technique using a standard JavaScript charting tool (Part 3).
