Node-RED is a flow-based development tool for visual programming developed originally by IBM for wiring together hardware devices, APIs and online services as part of the Internet of Things.

Node-RED provides a web browser-based flow editor, which can be used to create JavaScript functions. Elements of applications can be saved or shared for re-use. The runtime is built on Node.js and In 2016, IBM contributed Node-RED as an open source JS Foundation project.

There is plenty of information on the Internet about the Raspberry Pi, therefore, the scope of this section will not go beyond basic operation and wiring of the RsPi.

Note: RsPi is a minicomputer that runs on Linux.
