Overview of this book

In our modern, internet-connected world, where billions of devices constantly collect and send data to systems to be stored and processed, it’s surprising how the intricacies of data transmission and storage are often overlooked in the IoT domain. With Arduino Data Communications, you'll bridge the knowledge gap and become an expert in collecting data from IoT sensors, transmitting data, and configuring your own databases. This book is an exploration of IoT’s inner workings, guiding you through the process of setting up an end-to-end system that you can employ to prototype your own IoT solutions, using easy-to-follow examples. It begins with a general overview of the Arduino ecosystem, acquainting you with various sensors and shields and unveiling the art of data collection. You’ll then explore data formats and methods to store data, both locally and on database servers. As you progress through the chapters, you’ll learn how to set up REST and MQTT infrastructure to communicate with databases and get hands-on with LoRaWAN, Ethernet, cellular, HC-12, and RS-485. The final chapters are your training ground for real-world projects, imparting the essential knowledge you need to tackle complex challenges with confidence. By the end of this Arduino book, you'll have seamlessly configured an end-to-end system, all while immersing yourself in practical scenarios that bring the world of IoT to life.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “The first section, void setup() {}, holds code that will be run exactly once when the microcontroller boots up.”

A block of code is set as follows:

#include "Display.hpp" 
   void setup() { 
   Display::initialize(); 
   Display::print_lcd("Hello, world", "of embedded"); 
}
void loop() { 
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

#include "MyEnv.hpp" 
#include "MyNTPClient.hpp" 
#include <Arduino_MKRENV.h> 
#include <SPI.h> 
#include <SD.h> 

Any command-line input or output is written as follows:

mkdir MyAPI
cd MyAPI

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Click on Install, below the library provided by DFRobot.”
