Internet Shield Example

This example shows an application on 1Sheeld's internet shield

By using this example, you can use the voice recognition shield to say any country's name and 
get the status of its weather using the internet shield and the open weather map api and
based of the weather status (i.e. cloudy, sunny, snowy,... etc) an RGB LED changes its color.
 
OPTIONAL:
To reduce the library compiled size and limit its memory usage, you
can specify which shields you want to include in your sketch by
defining CUSTOM_SETTINGS and the shields respective INCLUDE_ define.
