Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol
#include<LiquidCrystal.h> //Library for LCD display function
LiquidCrystal lcd(12, 11, 5, 4, 3, 2); //Define LCD Module Pins tfor output so connect to digital pins RS,EN,D4,D5,D6,D7
int value1=A0; // inputs to analog pins
int value2=A1;
void setup() // function starts from here
{
lccd.begin(16,2);
}
void loop()
{
lcd.setCursor(0,0); //Sets Cursor at first line of LCD
lcd.print("Master "); //Prints in LCD
lcd.setCursor(0,1); //Sets Cursor at Second line of LCD
lcd.Print("SlaveVal: 99"); //Prints SlaveValue in LCD
