16x2 LCD Keypad shield for Arduino (Arduino Compatible) (screen)

This LCD Keypad Shield for Arduino features a blue-backlit 16x2 display with white characters and five control buttons. Based on the standard HD44780 controller, it allows you to add a local user interface to your Arduino projects without needing a computer connection.

The shield plugs directly onto standard Arduino boards (Uno, Mega, etc.), utilizing six digital pins (D4–D9 for LCD data/control, D10 and D12 for register select and enable) and one analog pin (A0) for the five keypad inputs. A built-in potentiometer allows you to adjust the display contrast.
