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.

Securing access – unveiling API keys and authentication

Before heading into the meat of the chapter, we first need to talk about the authentication mechanism of the platform. The Arduino IoT Cloud uses a token authentication mechanism to validate API requests. This involves the SDK/tool sending the Client ID and Client Secret to https://api2.arduino.cc/iot/v1/clients/token to get a token that is used later to authenticate for requests/responses.

Before we get started with the SDK installation and testing with Postman, we need to set up the API in the Arduino Cloud that will provide us the Client ID and Secret. In older versions of the interface, the API options are under the Integrations tab, but have now moved to the Arduino Cloud, which is available at https://cloud.arduino.cc/home/.

After visiting the Integration page click on API Keys and you will be taken to the API page. Click on CREATE API KEY. A popup will appear; provide a name for the API and click on the CONTINUE...
