Arduino IoT Cloud for Developers

By: Muhammad Afzal

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.

Delving into output controls

In the previous sections, we discussed input widget controls. Arduino IoT Cloud dashboards also feature stunning output controls. There are nine widgets here (although two are non-device widgetsmessenger and sticky note).

Value, status, gauge, percentage, and LED

Let’s start with the basic output widgets commonly used by developers in almost every solution. These output widgets are used to display a single value either in numerical or graphical format. Figure 3.9 shows all the main and basic output control widgets:

In this section, we will discuss in detail five different output widget controls in separate sections. First, we will start with the value widget control.

Value

The value widget is a very basic and important widget that is widely used in projects to display sensor/actuator values, such as temperature or humidity...
