Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol
master code: #include // library for LCD display function
LiquidCrystal lcd(12,11,5,4,3,2); //define LCD module pins
int val1=A4;
int val2=A5;
void setup()
{
lcd.begin(16,2);
}
void loop()
{
lcd.setCursor(0,0);
lcd.print(">>Master<<");
lcd.setCursor(0,1);
lcd.print("Slave Val:99");
delay(1000);
}
SLAVE CODE: #include
LiquidCrystal led(12,11,5,4,3,2);
int val1=A4;
int val2=A5;
void setup()
{
lcd.begin(16,2);
}
void loop()
{
lcd.setCursor(0,0);
lcd.print(">>Slave<<");
lcd.setCursor(0,1);
lcd.print("MasterVal:100");
delay(1000);
}
