9 Reasons You Should Start With This Book.

ArduinoJson Is Not Only A Good Library But Also A Trustworthy Piece Of Technology.

Whether you like it or not, most open source software is soon abandoned because the author loses interest in the project.

Just imagine, how stressful it would be if you open the source code of your project from a year ago and realize that you cannot compile it because some stupid piece of software is obsolete!

Well, with ArduinoJson, you shouldn’t worry about that.

Here’s why:

The only open source software that thrives is the one that has a sustainable model, either because a private company backs it, or because the author found an alternative way to earn money with the project.

The later is the reason why ArduinoJson is sustainable and will last long.

Selling this book is how the author earns a little money, and “buy” his time to develop the project. A contribution from people who purchase this book is what makes him able to continue developing this software.

That’s what makes ArduinoJson not only a good library but also a trustworthy piece of technology.

Learn From The Author Himself.

If you want to get started with ArduinoJson, this book is the shortcut to master the library.

Here’s why:

Inside this book, you’ll find a complete guide to master ArduinoJson, which is written by Benoit Blanchon, the author of ArduinoJson himself.

Just think of this: Learning ArduinoJson with this book will be like playing a video game with the creator of the game sitting beside you… and he tells you how to beat each level. Yes, you can beat the game quickly and easily!

Aside from that, Benoît has 30 years of experience in programming. So you know, learning from an experienced programmer like him will surely give you some amazing lessons.

It Covers Everything You Need To Learn - No Missing Pieces.

It’s designed to be read by anyone who wanted to learn with no advanced experiences required. Whether you’re a new developer who never used this library before, or you’re already using the library on your projects.

For the new user, it covers everything you need to learn to start from the very basic usage of the library. It gets you right to the code so you can start using ArduinoJson on your projects ASAP.

For you who already familiar with the library, this book will show you how to get the best performance and the most straightforward code.

What’s more, you’ll also find sample projects that will give you a sense of how the library should be used so you can optimize the usage of ArduinoJson on your projects.

Master The Library Faster And Avoid The Headaches.

Sure, to get started with the library is easy. In fact, you may be already playing with it for a while from any sources you can find online.

But learning through this way could be time-consuming.

There may be some missing information, that means you have to search for the answer in other sources. Yes, it could be really time-consuming.

With this book, you can avoid the headaches and make the learning process faster than learning from different sources.

There’s no need to browse all over the Internet to find something you don’t understand anymore. You can find everything you need to learn from this book.

The Best Way To Learn ArduinoJson.

The site arduinojson.org contains an exhaustive list of all the things in the library. Anyone who wants to learn the library for free, can simply go to the site and browse the content.

However, it’s not a tutorial to learn this library. There are many things separated anywhere.

Just like learning to speak from the dictionary. It’s possible, but it would be really hard. You have to put more effort if you want to learn ArduinoJson this way.

Well, you can also learn from a free tutorial on other sites, but that’s second-hand information. And just like you’ve been read above, there could be some missing pieces of information. (That’s what you should expect from a free tutorial site, right?)

On the other hands, this book is well-written and designed to be a step-by-step guide to master ArduinoJson. The information is first-hand information that you’ll get from the author of ArduinoJson himself.

Get A Quick-Refresher In C++.

Benoît Blanchon realizes that there are many Arduino users who lack some of the fundamental principles of C++. That’s why he includes a section where you can get a quick-refresher in C++.

Now, that would be utterly crazy of him to try to teach C++ from scratch; it would be way too long and there are many excellent resources for that. Instead, he focuses on the pieces that are often misunderstood by Arduino users.

He called this section “The Missing C++ Course” because it covers holes left by the other Arduino books.

Here’s what’s really interesting…

There are many readers who thanked Benoît Blanchon for The Missing C++ Course. It’s so useful for them, and some of them even said that this book worth-having even for The Missing C++ Course only.

Well, that could be a big reason why you should read this book today.

Optimized For Fast And Easy Reading.

Just because this book is written by a programmer, you won’t find it’s boring and far from being easy-to-understand.

In fact, it uses short sentences, active voice, and conversational style, to ensure a smooth understanding, even if you’re a non-English speaker.

If you hate reading, the good news is…

You can finish it fast without losing comprehension. Because that’s how the book is designed. It’s optimized for fast and easy reading.

This book is also well segmented, so you can quickly skim when you are looking for something in particular.

Designed To Be Read Anywhere Even While You’re Away From The Computer.

Don’t have too much time to read this book?

No worries. This book is designed to be read from cover to cover without a computer. That means while you’re in commute, instead of playing with your smartphone, you can spend your time reading this book.

What’s more, it comes in several formats: .pdf, .epub, and .mobi. Just transfer it to your phone or tablet, and you can read it with your favorite reading app anytime and anywhere.

Master The Library And Support The Development.

By purchasing this book, you can master the library in the shortest way possible, while also supporting the author to keep developing the software.

Just like what you’ve read earlier, a contribution you make from purchasing this book is what allows the developer to continue developing this project.

So if you love this software and want to encourage the author to keep developing and maintaining the library, just purchase this book as a way to say thanks to him.

What’s Inside The Book?

This book is not a compilation of resource already available online.

In fact, it’s first-hand information and all the content is new - written specifically to be a step-by-step guide to mastering ArduinoJson.

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.

That’s how the author is dedicated his time to write this book. He’s not just copying and paste the information you could find for free, and take your money. That’s not how it works.

In fact, he wanted to make sure this book could really become the best way to master ArduinoJson, and you’ll get huge benefits from it.

About The Author

Meet the guy who dedicates most of his time to develop this library, and yeah, another big portion of his time to write this amazing book.

Well, at first, we decided to write it in third person view… For one purpose: To make it sounds more professional.

But, we think it’s better if Benoît himself who write this section, so it will be like a letter from a friend… which in my way, it is.

So there you go. Here’s what Benoît want to say to you:

Hello there,

My name is Benoît Blanchon, the author of ArduinoJson, and the author of this book - Mastering ArduinoJson.

In case this is the first time you ever heard of me, here’s a little about me and my life as a programmer.

I’ve been writing code since the early nineties, that’s almost 30 years of experience in programming.

OK, only 20 years counts as professional experience, but to me, the first 10 years is probably the most important part of my life.

That’s when I learned to program by myself, reading books and trying stuff, just like the most of you. This experience helped me find a job, years before I graduated.

Anyway, I wrote this book because I clearly understand how learning from various sources of information could make you feel overwhelmed. It could be stressful and time-consuming.

So I made this book to be a shortcut for anyone who wanted to learn how to use ArduinoJson in the fastest time possible, and avoid the headaches.

I putted a lot of energy in this book, you wouldn’t believe the time I spent planning, writing and editing. But now that I see the results and all the positive feedback, I see that it was worth the effort.

But I know some of you may use this software for learning, not for a professional work… Which is why I sell this book at a reasonable price that could be affordable for anyone.

So if you want to learn and master this library, I highly recommend you to start with this book. If you want to show you gratefulness for all the work around ArduinoJson, please purchase this book and encourage further developments.

Sincerely,

Benoît Blanchon

P.S. Please understand that it is a huge commitment to be the developer of a successful open-source project.

In seven years, I published a hundred releases, answered thousands questions, built a dedicated website and created a tool (the ArduinoJson Assistant) that writes the code for you.

That’s literally thousands of hours of work and dedication.

Well, to answer even a single question it often takes more than one hour.

Why?

The reason is that, I always want to provide the right answer to your question in a single answer… so you can save your time and move on to your projects quickly. Yet, I always try to give an answer in less than 24 hours, which is very rare for open source software.

With ArduinoJson, you get a professional grade customer support for free!

However…

As this software becomes more popular, and the more people starting to use it… I have to spend more time on this project than working on my professional work.

Honestly, I’d love to continue working like that, but in reality, it’s not possible for me. It would be possible if only I manage to generate a continuous income.

That’s why I decided to sell this book so I can continue to dedicate most of my time to this project… and you can keep using this library - including the website, tools, and customer support for free.

You see, it’s a win-win solution for both of us.

And remember, for a very small investment, not only you can “buy” my time to continue working on this project, but you’ll also get a very good book.
