16×2 LCD Arduino Keypad Shield Module

The 16×2 LCD Arduino Keypad Shield Module combines a two-line character display with a five-button navigation keypad on a single plug-on shield. Instead of wiring an LCD module separately, connecting a contrast potentiometer, and routing individual button inputs through resistor dividers, this shield handles all of that on the PCB itself. You stack it onto an Arduino Uno, Mega, or Leonardo, include the LiquidCrystal library in your sketch, and the display is ready to use.

The LCD shows 16 characters across two rows — enough for most status messages, sensor readings, menu labels, and user prompts. The five keypad buttons — Up, Down, Left, Right, and Select — are all read through a single analog pin using a resistor ladder, which keeps digital pin usage on the Arduino to a minimum.

The backlight is adjustable, which is useful in projects where the display needs to be readable in varying ambient light conditions.

LCD Arduino Keypad Shield Module For IoT project developers and students build a simple human interface layer on top of an Arduino project — a menu system, a settings screen, a sensor readout display — this shield is a direct and practical solution. StemVolt provide this module ready to ship for your next build.

Features:

• Integrated LCD and Keypad — Both display and input buttons are mounted on a single PCB shield
• Single Analog Pin — All five keypad buttons are read through one analog input using a resistor divider network, preserving digital I/O pins for other uses
• Standard LiquidCrystal Library Compatible — Works with the built-in Arduino LiquidCrystal library without any additional drivers
• Adjustable LCD Backlight — Brightness can be controlled in firmware or via hardware to suit ambient lighting conditions
• 5V Operation — Powered entirely from the Arduino — no external power supply or voltage regulator required

Technical Specifications:

Applications:

• Menu-Based User Interface — Build multi-level settings menus for your Arduino project using the five navigation buttons and display rows for option labels
• Real-Time Clock Display — Pair with a DS1307 or DS3231 RTC module to show live time and date on the LCD for clock and projects
• Sensor Data Readout — Display live readings from temperature, humidity, pressure, or distance sensors directly on the 16×2 screen
• IoT Device Control Panel — Use as a local interface for IoT project builds where the user needs to view status or adjust settings without a phone or web dashboard
• Educational Prototyping — Teaches students how LCD parallel communication, resistor-ladder button reading, and UI design work together in a single, self-contained shield
