Control room temperature with Arduino IoT Cloud

4  Arduino IoT Cloud Variables description
5
6  The following variables are automatically generated and updated when changes are made to the Thing
7
8  float temperature;
9  bool fan;
10  bool heating;
11
12  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
13  which are called when their values are changed from the Dashboard.
14  These functions are generated with the Thing and added at the end of this sketch.
