ArduinoJson.h is a C++ library that allows you to parse and generate JSON (JavaScript Object Notation) data with Arduino or any other C++ compatible platform. It is an efficient and flexible library used to handle JSON data, making it easier for developers to work with JSON.
To use ArduinoJson.h, you must download and install it into your Arduino IDE. You can do this by following these steps:
Sketch
from the menu.Include Library
.Manage Libraries
.ArduinoJson
.Install
and wait for installation to complete.Here is an example of how you can use ArduinoJson.h to generate and parse JSON data.
In this example, we create a JSON object doc
, add data to it, generate JSON data from it using serializeJson()
, and parse the data using deserializeJson()
. We then access the data in the JSON object using array syntax.
ArduinoJson.h is a powerful library that makes working with JSON data in C++ a breeze. Its simple and flexible API makes it easy to generate and parse JSON data, and its low memory footprint makes it ideal for use in embedded systems.
