How to install

There are several ways to install ArduinoJson, from simpler to more complex:

  1. Use the Arduino Library Manager
  2. Download ArduinoJson-v6.6.0-beta.h put it in your project folder
  3. Download ArduinoJson-v6.6.0-beta.zip and extract it in you libraries folder

Note: ArduinoJson-v6.6.0-beta.h are ArduinoJson-v6.6.0-beta.hpp are almost identical; the difference is that the .hpp keeps everything in the ArduinoJson namespace.
