Mastering ArduinoJson

Although it does not contain an exhaustive list of function like this page, the ArduinoJson ebook is a more convenient and more pleasant way to learn how to use the library.

It contains step-by-step tutorials to learn how to serialize or parse JSON with ArduinoJson. It also explains how StaticJsonBuffer and DynamicJsonBuffer work, and how to choose between them.

If C++ is not your strength, you will appreciate the quick C++ course which will help you catch up with pointers, references, and other subtilities.
