About this project

Get current weather data for a particular city on Earth from OpenWeatherMap.org.

How it works

Connect to the openWeatherMap API https://openweathermap.org/.

You have to sign up and create API key to get current weather data.

Data is in JSON, XML, or HTML format. In this project, I use JSON format.

So you should download a libarary called ArduinoJson version 5.
