Welcome back to our second article about creating a robust, bidirectional IoT prototype in less than a day using Arduino, Heroku, and Node-RED. If you missed the first part, we covered setting up Node-RED, adding security, and deploying to Heroku. In this article we’ll look at creating our embedded system on the Arduino boards, connecting them to our Node-RED instance, customizing Sketches, and creating a flow that allows our devices to talk to each other. Let’s get started.
What is Arduino IoT Cloud?
To connect the physical devices (boards) to the internet we will use Arduino IoT Cloud, a device manager, and data visualization tool. After setting up an account at https://create.arduino.cc, we can create our first digital twin.
