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.
