+/**
+ *  This program is an advanced "IoT" thermometer using LM75B component library.
+ *  It displays the current value to the Serial host in Celcius or Fahrenheit (possible to change using a switch).
+ *  It also stores an historic and displays it to the user using the LCD screen.
+ *  Moreover, you can change the orientation of the screen by turning the device (just like a smartphone)
