Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol

Interfacing a 16*2 LCD with Arduino using I2C protocol

Master code:

#include<LiquidCrystal.h>

LiquidCrystal lcd(13, 12, 8, 7, 4, 2);

int data1=A4;

int data2=A5;

void setup()

{

lccd.begin(16,2);

}

void loop()

{

lcd.setCursor(0,0);

lcd.print("Master");

lcd.setCursor(0,1);

lcd.Print("Slave data");

LCD

delay(1000);

}

Slave Code:

#include<LiquidCrystal.h>

LiquidCrystal lcd(13, 12, 8, 7, 4, 2);

int data1=A4;

int data2=A5;

void setup()

{

lcd.begin(16,2);

}

void loop()

{

lcd.setCursor(0,0);

lcd.print("Slave");

lcd.setCursor?(0,1);

lcd.print("Master data");

delay(1000);

}
