  Arduino IoT Cloud Variables description 

 
 

  The following variables are automatically generated and updated when changes are made to the Thing 

 
 

  float moisture; 

  CloudLight lED; 

  CloudTemperatureSensor temperature; 

  CloudRelativeHumidity humidity; 

 
 

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions 

  which are called when their values are changed from the Dashboard. 

  These functions are generated with the Thing and added at the end of this sketch.
