About the Book

Who is this book for?

If you never used ArduinoJson, you will appreciate this book because it guides you through your learning. It starts with the basic usage of the library and increments the complexity step by step. The last chapter analyzes several example projects and explains the design choices. It is a much better way to learn than blindly copy-pasting the examples.

If you are already using ArduinoJson, you will learn how to get the best performance and the most straightforward code. You will discover that many examples found on the Internet are suboptimal and even dangerous. The sample projects will give you a sense of how the library should be used and will give you a new perspective on your projects.

What knowledge is required?

This book is not a course on Arduino or embedded programming. It assumes a small experience with Arduino; you do not need to be a master, just to be able to compile and run a simple sketch.

Many Arduino users lack some of the fundamental principles of C++, that is why this book starts with a quick refresher. However, it does not pretend to teach C++ from scratch; it assumes the knowledge of another object-oriented programming language, such as C# or Java. There is much material to learn how to program with Arduino, but most of them miss essential parts that are crucial in your development career. This chapter covers the holes left by the other Arduino books, that is why I called it "The Missing C++ Course."

What is in the book?

This book is not a compilation of resource already available online. All the content is new, and nothing was recycled from existing documents.

It contains many new code samples and original illustrations. 

Contrary to the documentation on arduinojson.org, which grew organically from the GitHub wiki, this book is the result of several months of continuous work, starting from scratch. The result is a coherent and complete learning material.

How is the book written?

This book is optimized for fast and easy reading. It uses short sentences, active voice, and conversational style, to ensure a smooth understanding, even for non-English speakers.

The book is well balanced between text and code. Code snippets are short and focused, so there are easy to digest, but the complete programs are available in the zip file.

The book is designed to be read from cover to cover without a computer, so it is the perfect format to learn in your commute. It is also well segmented, so you can quickly skim when you are looking something in particular.

Why buy this book?

By buying this book, you encourage the development of high-quality libraries. By providing a (modest) source of revenue for open-source developers like me, you ensure that the libraries that you rely on are continuously improved and won't be abandoned after a year.

The current version of the book covers ArduinoJson 5.13, but you will have access to newer revisions as soon as they exist. You only have to buy this book once, you won't have to pay for upgrades.

Just bought your Arduino JSON book on Amazon. I learned more in the hour it took me for reading your book than in 3 courses in University... I wanted you to know that if you write a C++ book for Arduino or any other book, I will be pleased to purchase those as well.

Mr. Blanchon's book is one of the best JSON books available to date! It gets right to the code without playing in tall grass, letting new developers get right to the good stuff.

An excellent in-depth book that combines Micro-controllers and JSON instructions. This ebook was exactly what I needed to get started with the JSON, Arduino & ESP

The short C++ section was a great refresher. The practical use of ArduinoJson in small embedded processors was just what I needed for my home automation work. Certainly worth having! Thank you for both the book and the library.

I especially loved the explanations on C++ syntax. A lot of things snapped into place in my head I wasn't expecting. Well done and thank you! Original reason I bought the book was to support the development and also to find out the design decisions on the ArduinoJson syntax which TBH got me interested in learning C++11/14 for my Arduino projects.

Great book for learning how to use AruinoJson. But also a good, quick course on C++ pointers, buffers etc.

I have been a casual user of the Arduino IDE for about 6 months, and tend to struggle with why I needed to define variables and constants in specific ways, and the general construction of programs in this environment. The book provides enough "why" to remove mystery from the organization of data and program spaces in the microcontroller environment to make me much more comfortable.

Excellent approach of the programming. It goes a step forward for the programmer in C++ and enforce some knowles. Highly recommended. Ezequiel from Argentina
