No coding required: Node-RED on a Raspberry Pi |

Node-RED is an easy-to-use programming tool that can be used for handling IoT signals. This article shows that Node-RED can also be used to quickly integrate and test hardware devices. As you can see from this tutorial, connecting and testing a cellular mode with Raspberry Pi using Node-RED required no coding at all.

For more information about Node-RED and other ways it can be used, visit the project’s website and my earlier Node-RED posting.

    How to Node-RED!

    This video shows shows how to configure Node-RED on the Raspberry Pi and how to start creating home automation projects using MQTT and Node-RED. Some practical IoT examples are show.

    Wiring The Internet of Things With NODE RED

    The Internet of Things is not a single choice of technology, approach or philosophy. It brings together multiple platforms, products and protocols, where the whole is greater than the sum of its parts. One of the challenges of IoT is to make it as easy as possible to allow developers to create things, for play or profit, serious or whimsical, professional or hobbyist. Node-RED is an open-source visual tool for wiring the Internet of Things. Built on top of node.js, it provides a light-weight, browser-based editor that makes it easy to integrate different streams of both physical and digital events. This session explores what Node-RED can do, showcases how it has been used to great success across a range of industries and looks to the future of the project.

    Visual Raspberry Pi With Node-Red And TensorFlow

    If you prefer to draw boxes instead of writing code, you may have tried IBM’s Node-RED to create logic with drag-and-drop flows. A recent [TensorFlow] video shows an interview between [Jason Mayes] and [Paul Van Eck] about using TensorFlow.js with Node-RED to create machine learning applications for Raspberry Pi visually. You can see the video, below.
