LCD Keypad Shield 1602

The LCD Keypad Shield 1602 is a versatile and beginner-friendly display module designed for use with Arduino Uno, Mega, and other compatible boards. It features a 16×2 character LCD and 5 onboard push buttons (Select, Up, Down, Left, Right), along with a Reset button.

This shield is ideal for projects that need a simple user interface. You can use it to display sensor data, navigate menus, or show system status without needing a separate screen and button setup. Thanks to the LiquidCrystal library, it’s easy to program and integrate.

One key benefit of this shield is that it uses only 6 Arduino pins (digital pins D4–D10), freeing up others for sensors or modules. The buttons share a single analog pin using a voltage divider, simplifying input wiring. There’s also a potentiometer onboard to adjust LCD contrast easily.

Whether you’re building a thermostat, data logger, automation panel, or an educational tool, this shield is a plug-and-play solution for displaying and controlling your Arduino-based systems.

You can pair this shield with components from our Arduino and Accessories and Electronics Components sections for full-featured projects.
