₹210.00₹220.00 excl GST (-5%)
Arduino-compatible 16×2 LCD Keypad Shield with Blue Backlight. Features 5 navigation buttons using only 1 Analog pin. Ideal for menu interfaces and DIY projects.
Create interactive menus and displays in seconds with the 1602 LCD Keypad Shield for Arduino. This popular shield is the easiest way to add a user interface to your project, combining a crisp 16×2 Character LCD with a 5-button keypad on a single board that plugs directly into your Arduino Uno or Mega.
Pin-Saving Design
Navigating menus usually requires many wires, but this shield is designed to be efficient. The entire keypad (Select, Up, Right, Down, Left) uses just one Analog Pin (A0) through a clever 5-stage voltage divider circuit. This leaves your digital pins free for sensors, motors, and other modules.
Plug & Play Compatibility
The shield is designed to snap right onto standard Arduino headers. It comes with the standard 4-Bit Arduino LCD Library support, meaning you can use the built-in LiquidCrystal library examples to get text on the screen instantly. It also features a Reset Button on the top for easy code restarting and an onboard potentiometer to fine-tune the display contrast.
Key Features
Sharp Display: 1602 Industrial Character LCD with white text on a blue backlight.
Integrated Keypad: 5 keys (Select, Up, Down, Left, Right) for easy menu navigation.
Efficient I/O: Uses only Digital Pins 4, 5, 6, 7, 8, 9, 10 for the LCD and Analog Pin 0 for buttons.
Contrast Control: Built-in potentiometer to adjust screen clarity.
Expansion Pads: Breakout pads for unused pins are exposed for easy soldering of extra sensors.
Reset Button: Dedicated button to reset your Arduino without unplugging power.
