<br>
==Introduction==
This is a basic 16 character by 2 line LCD display module.<br>
The LCD module displays white text on blue background, and comes with I2C communication interface.<br>
You can use only one line to connect it to microcontroller’s I2C communication interface.<br>
On the back comes with a potentiometer, which can be used to adjust the backlight, with default address 0x27.<br>
It is very easy for you to connect the module to control board for communication using only an RJ11 cable 

<span style=color:red> '''Special Note:''' <br>
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface. <br> If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module. </span><br>
<br>

#include<LiquidCrystal_I2C.h>  // Place “LiquidCrystal_I2C.h” under the directory “library” of Arduino
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
lcd.init();// Print a message to the LCD.
lcd.backlight();
lcd.setCursor(2,0);
lcd.print("Hello, world!");

==Test Result==
Initially, you should see the words “hello, word!” and “keyestudio!” pop up on your LCD.<br>
Remember you can adjust the contrast using the potentiometer on the module back if you can’t make out the words clearly.
