CODE EXPLANATION
• #include <LiquidCrystal.h> Calling a library allows us to use
some functions to command the LCD.
• LiquidCrystal lcd(12, 11, 5, 4, 3, 2) Maps the physical pins with
the pins defined in the library.
• Serial.begin(9600) Initializes the serial port. 9600 is the rate,
in Bauds, at which data are transmitted over the bus.
• lcd.begin(16, 2) Initializes the LCD and specify the dimensions
of the screen. Here we use a 16 columns and 2 rows LCD screen.
