Node-RED is a programming tool for working with hardware devices in a WYSIWYG (What You See Is What You Get) style. It allows developers to create work flows for everything from websites to integrated devices using a series of connected nodes designed in a browser. The Node-RED interface can make learning to work with hardware much more simplistic and can get novices started much more quickly. It can also be used by professionals that want to have a better way of quickly designing projects without all the boilerplate a normal project may incur.

Using Node-RED we will move through several different project types including the always simple "Hello Blinky", all the way up through a basic web api that can be used with a smart home. We will be using both the Raspberry Pi 3 and Arduinos to control the different components, and we will be showing how to communicate with the different pieces individually. Want to have a Raspberry Pi controlling connected arduinos? How about a smart home system that can communicate with individual sensors? What about a smart garden that can monitor your plants' water levels and report back to your watering system? With Node-RED, it's just a matter of dragging around a few UI items.
