-  The following variables are automatically generated and updated when changes are made to the Thing properties
-
-  bool switchButton;
-
-  Properties 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.
+  This sketch demonstrates how to use more complex cloud data types such as a colour or coordinates.
 
   This sketch is compatible with:
-    - MKR 1000
-    - MKR WIFI 1010
