LCD Keypad Shield For Arduino

An Arduino-compatible LCD shield with integrated keypad for creating user-friendly interfaces. Features a 1602 LCD with white characters on blue backlight, plus a 5-button navigation keypad for menu selection and control.

The clever design uses only one analog pin (A0) for all five buttons via a voltage divider circuit, saving digital I/O pins for your project. Includes an onboard potentiometer for contrast adjustment.
