Raspberry Pi and Node-RED: A perfect match for IoT projects
How to Download Node-RED for Raspberry Pi
Node-RED is a powerful open-source tool for visual programming to build Internet of Things (IoT) applications. It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.

If you have a Raspberry Pi, you can use Node-RED to create and run IoT applications on the edge of the network, taking advantage of its low-cost hardware, event-driven model, and large ecosystem of modules. In this article, we'll show you how to download and install Node-RED on your Raspberry Pi, and how to create your first flow.
Before you start, make sure you have the following:
A Raspberry Pi with Raspberry Pi OS installed. You can use any model of Raspberry Pi, but we recommend using Raspberry Pi OS Bullseye as the currently supported version.
A power supply, a micro SD card, a keyboard, a mouse, and a monitor for your Raspberry Pi. Alternatively, you can use SSH or VNC to access your Raspberry Pi remotely.
An internet connection for your Raspberry Pi. You can use Ethernet or Wi-Fi.
The easiest way to install Node-RED on your Raspberry Pi is to use the install script provided by Node-RED. This script will install Node.js, npm, and Node-RED as global modules, along with some useful Pi-specific nodes. It will also set up Node-RED to run as a service that can be started and stopped easily.
To run the install script, open a terminal window on your Raspberry Pi and enter the following command:
