Node Red Dashboard for Raspberry Pi
Node-RED is a programming tool for wiring together hardware devices, APIs and online services.
It was developed as a visual programming tool for the Internet of Things. It also allows you to produce and publish a funky web based dashboard with one click.
Node-RED includes a browser-based editor that makes it easy to wire together flows using the selection of nodes in the side menu. Flows can be then be deployed to run in a single-click. JavaScript functions can be created within the editor to customise the messages passed between nodes. A built-in library allows you to save useful functions, templates or flows for re-use. The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run on low-cost hardware such as the Raspberry Pi as well as in the cloud. Nodes can be anything from a timer to trigger events to a Raspberry Pi GPIO output used to turn on a LED (or salt lamp in our example). With over 225,000 modules in Node’s package repository, it is easy to extend the range of nodes to add new capabilities. As we will demonstrate there are packages available for the Raspberry Pi and Sense Hat. The flows created in…
