My name is Jerry Wasinger and about six years ago I started developing a line of products for the Raspberry Pi called Pi-Plates:
These are a family of stackable and interchangeable add-on boards that provide affordable data acquisition and control functions (DAQC) for both general purpose and industrial applications. Thanks to the efforts of Mike Harsch and others, they are supported by an expanding palette of nodes for Node-RED. To help y'all get started (we're based in Georgia), we have written a couple of simple tutorials on using Node-RED with Pi-Plates. The first explains the basics while the 2nd one focuses on adding a simple dashboard. Check them out at:
There is more to come so let me know if you have any comments or suggestions.
