==Introduction==
keyestudio 2004 I2C Module is a 20 character by 2 line LCD display with Blue background and White backlight. The original 2004 LCD needs 7 IO ports to be up and running, ours is built with Arduino IIC/I2C interface, saving you 5 IO ports. This LCD is ready-to-use because it is compatible with the Arduino Liquid Crystal Library.<br>


==Specification==
* Interface: I2C
* I2C address: 0x27
* Operating voltage: +5V
* Size: 27.7mm×42.6mm
* Contrast control: through potentiometer


==Connection Diagram ==
This module carries I2C interface, so we need to comply with I2C protocol in usage and corresponding head files must be included and added into the library. <br>

Below is the connection diagram between this module and Arduino controller:<br>

==Sample Code==
<pre>
//YWROBOT
//Compatible with the Arduino IDE 1.0
//Library version:1.1
#include <Wire.h> 
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27,20,4);  // set the LCD address to 0x27 for a 16 chars and 2 line display


void setup()
{
  lcd.init();                      // initialize the lcd 
  lcd.init();
  // Print a message to the LCD.
  lcd.backlight();
  lcd.setCursor(3,0);
  lcd.print("Hello, world!");
  lcd.setCursor(2,1);
  lcd.print("Hello，keyestudio!");
   lcd.setCursor(0,2);
  lcd.print("Arduino LCM IIC 2004");
   lcd.setCursor(2,3);
  lcd.print("Power By Ec-yuan!");
}
void loop()
{
}
</pre>
Note: To ensure that this module will work properly, these two head files, namely Wire and LiquidCrystal_I2C, must be added into our library before code test.<br>
