Node-RED

Node-red is a programming tool that makes it easy to control things on the internet. It's like a program (or "app") that lets you create special tasks or rules that can be used to control things like lights, sensors, and other devices when they're connected to the internet. You can think of it like a toolkit where you can collect different parts that connect to each other. Node-red is like a giant puzzle that you can put together to do things online.
