How to Build a Robust IoT Prototype In Less Than a Day (Part 2)

(Part 1 is here.)

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.
