OpenWeatherMap - very complex/multilevel Json data.

Created by: ethelder

Hello,

I'm trying to work with API for weather forcasting and had problems parsing data about weather id from this api call (9 hours ahead) :

    }
  ]
}

I want to get all of the weather id's and than to find out - will it be raining:) I know you have an example of "complex" in your wiki, but using JsonArray I still had problem parsing the value. I started a thread on Arduino forum as well. https://forum.arduino.cc/index.php?topic=357973.new

BTW - your example doesn't work on Arduino Yun until you add a while(!Serial) loop in setup.

Thanks for any help in advance.
