Read MoreNode-RED for rapid hardware wiring
I will be posting few interesting follow-up posts that are based on tool for wiring together hardware devices called Node-RED. This post will serve as a reference how to prepare Raspberry Pi and install dependencies. Besides usual IoT stuff (sensor serving, data collection, aggregation and decision making) I see great opportunity to use node-red in rapid […]
