Introduction

This is another great blue/yellow backlight LCD display. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.

Features

• Interface: I2C
• I2C Address: 0x27
• Pin Definition : VCC、GND、SDA、SCL
• Back lit (Green with white char color)
• Supply voltage: 5V
• Size : 27.7mm×42.6mm
• Contrast Adjust : Through Potentiometer
• Only employ two I/O interface

Example code

Download Arduino 1602 I2C library

#include <Wire.h> 
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27,16,2);  // set the LCD address to 0x27 for a 16 chars and 2 line display
void setup()
{
 lcd.init();                      // initialize the lcd 
 // Print a message to the LCD.
 lcd.backlight();
 lcd.print("Hello, world!");
}
void loop()
{
}
