Overview of this book

The Arduino IoT Cloud offers a variety of features for building modern IoT solutions while reducing time and costs for prototyping and deployment. This book is a step-by-step guide, helping you master the powerful Arduino IoT Cloud ecosystem. This book begins by introducing you to the IoT landscape including its architecture, communication technologies, and protocols and then to the capabilities of the Arduino IoT Cloud platform and the Cloud Editor. With practical projects, such as monitoring air quality, building a portable asset tracker, and creating a remote alarm system using the LoRaWAN specification, you'll learn how to implement real-world IoT applications. Next, you'll explore communication between IoT devices and cloud platforms as well as the implementation of the Arduino IoT Cloud SDK and JavaScript for advanced customization. You'll also find out how to program IoT nodes, analyze the surrounding environment data, and visualize it on dashboards. Additionally, you’ll get to grips with advanced features such as task scheduling, synchronization, remote over-the-air updates for IoT nodes, and scripting with CCLI, through hands-on examples. By the end of this book, you’ll have learned how to work with the Arduino IoT Cloud platform and related hardware devices and will be able to develop industry-specific and cost-effective IoT solutions, such as smart homes and smart agriculture.

The Arduino IoT Cloud and a Node-RED Hello World example

In this section, we will build on our project by adding some extra functionality to our system via Node-RED. This will help you to understand how you can use Node-RED to integrate non-compatible devices with the Arduino IoT Cloud.

Node-RED will monitor the LED status based on a value that is either true or false. On the basis of this status, Node-RED will send the command to another Thing variable called LEDStatus, which will be linked to the Status widget, which shows the LED as being either on or off. Using this example, you will learn how to read data from a Thing property/variable and how to write data to a Thing property/variable.

Node-RED has a module that was officially developed by Arduino for connectivity with the Arduino IoT Cloud. It provides five nodes to carry out different types of operations. For further details, visit https://flows.nodered.org/node/@arduino/node-red-contrib-arduino-iot-cloud.
