The Internet of Things is not a single choice of technology, approach or philosophy. Its very existence is the bringing together of 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 make 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. Its lightweight nature makes it ideal to run at the edge of the network, such as on the Raspberry Pi. By making use of the huge module ecosystem within node.js, it provides a framework for easily adding new nodes into its palette to extend its capabilities.
This session introduces Node-RED, demonstrates what it can do and how it can be easily extended.
