CAUTIONS

• The LCD panel is made by glass. Any mechanical shock (eg. dropping from high place) will damage the LCD module.
• Do not add excessive force on the surface of the display, which may cause the Display color change abnormally.
• The polarizer on the LCD is easily get scratched. If possible, do not remove the LCD protective film until the last step of installation.
• Never attempt to disassemble or rework the LCD module.
• Only Clean the LCD with Isopropyl Alcohol or Ethyl Alcohol. Other solvents (eg.water) may damage the LCD.
• When mounting the LCD module, make sure that it is free form twisting, warping and distortion.
• Ensure to provide enough space(with cushion) between case and LCD panel to prevent external force adding on it, or it may cause damage to the LCD or degrade the display result.
• Only hold the lCD module by its side. Never hold LCD module by add force on the heat seal ot TAB.
• Never add force to component of the LCD module. It may cause invisible damage or degrade of the reliability.
• LCD module could be easily damaged by static electricity. Be careful to maintain an optimum anti-static work environment to protect the LCD module.
• When peeling off the protective film from LCD, static charge may cause abnormal display pattern. It is normal and will resume to nomal in a short while.
• Take care and prevent get hurt by the LCD panel sharp edge.
• Never operate the LCD module exceed the absolute maximum ratings.
• Keep the signal line as short as possible to prevent noisy signal applying to LCD module.
• Never apply signal to the LCD module without power supply.

STEP-1 RECEIVER CODE

Before uploading the given code , Download this Library

http://www.resistorpark.com/arduino-virtualwire-library-download/

#include //install this library from given link

#include //Install this inbuilt library

LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

char cad[100];

int pos = 0;

void setup()

{

lcd.begin(16, 2);

lcd.setCursor(1, 0);

vw_setup(2000);

vw_rx_start();

}

void loop()

{

byte buf[VW_MAX_MESSAGE_LEN];

byte buflen = VW_MAX_MESSAGE_LEN;

int i;

if ( vw_get_message(buf, &buflen) )

{

if (pos < 2)

lcd.setCursor(0, pos);

else

{

pos = 0;

lcd.clear();

}

for (i = 1; i < buflen; i++)

{

lcd.print((char)buf[i]);

pos++;

}}}

STEP-3 TRANSMITTER CODE

#include //install this library

char cad[100];

int i=0;

void setup()

{

Serial.begin(9600);

vw_setup(2000);

Serial.print("End with "." each data");

}

void loop()

{

if( Serial.available() > 0)

{

cad[i] = Serial.read();

i++;

}

if( cad[i-1] == '.')

{

cad[i] = '';

i=0;

vw_send((byte *)cad, strlen(cad));

delay(400);

}

}
