  Arduino IoT Cloud Variables description

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

  int humidity_1;
  int humidity_2;
  bool motor_1;
  bool motor_2;
  bool motor_3;

  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.

// for example:  when temperatrue is 25 degree, the NTC's resistor number is 10000.0 ohm, so the adc number will be:
//  10000.0 / (10000.0 + 10000.0) = 512, so, if you reading from adc and get 512 +/- 10 equals 25 degree.
