Product Description
16×2 (1602) LCD Keypad Shield – Blue Backlight for Arduino
Product description:
The 16×2 Keypad LCD Shield is a compact and user-friendly interface for Arduino projects, combining a 2×16 character LCD with six built-in push buttons. It connects to the LCD using digital pins 4–10, while all button inputs are read through a single analog pin (A0).With features like contrast adjustment, backlight control, onboard power LED, and access to five extra analog pins, it is ideal for projects requiring menus, sensor monitoring, debugging, or simple user interaction—without the need for external switches or complex wiring.
