Sketch generated by the Arduino IoT Cloud Thing "Untitled"
https://create.arduino.cc/cloud/things/dd6e31cb-a4eb-4994-ad6b-a1f275aa6aed
Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
int charge;
int fanspeed;
int rotaspeed;
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.
