  • Now we add the display and connect it to 5V (second pin) and Ground (first pin).
  • We connect the third pin of the LCD to the "wiper" (middle pin) of the potentiometer.

  • Now it's time to connect the data pins! The list that follows is: Display Pin → Arduino Pin
  • 4 → 12
  • 5 → 11
  • 6 → 10
  • 7/8/9/10 = No connection
  • 11 → 7
  • 12 → 6
  • 13 → 5 and 14 → 4
