The LiquidCrystal.h Library will use the ESP32 pins as follow to send information to the LCD:
  - Pin 13 (RS) to indicate if a Command (LOW) or Data (HIGH) will be received by the LCD.
  - Pin 12 (EN) to Enable (activate / HIGH) the LCD to receive Command or Data from the ESP32.
  - Pin 25, 26, 27 & 14 to sent the Command or Data to LCD.
