IoT, APIs und Microservices - alles unter Node-RED
0 likes404 views
This document discusses Node-RED, an open source visual tool for wiring together hardware devices, APIs, and online services. It provides an overview of Node-RED, how to install it, how to create flows by connecting nodes, and how to install additional node modules. It also discusses using Node-RED with Arduino boards and the YaaS API. Developers can build their own nodes by writing JavaScript code.
