This sample shows how to call[Firebase](https://www.firebase.com/) from the[ESP8266 Arduino core](https://github.com/esp8266/Arduino).

FirebaseArduino is a library to simplify connecting to the Firebase cloud database from

arduino clients.

It is a full abstraction of Firebase's REST API exposed through C++ calls in a wiring

friendly way. All Json parsing is handled by the library and you may deal in pure C/Arduino

types.
