Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol
Overview of the Project:
In this project implementing the Code for “Interfacing a 16*2 LCD with two Arduino’s (one for Master and one for Slave) using Inter-Integrated Circuit (I2C) communication protocol” by sending the message to LCD using I2C communication protocol and display the message on LCD screen.
Goals:
- Communication between Arduino and 16*2 LCD using I2C protocol.
- Displaying the message sent by Master and received by slave i.e. LCD display.
Key Highlights of the Project:
- Using the inter-integrated circuit communication protocol, transferring the data i.e. the message we want to display is sent to the LCD.
- Two Arduino’s connected to the LCD display and the communication is executed using I2C protocol between Arduino and the LDC display.
Deliverables of this project:
- Communication between the Arduino’s and LCD using I2C.
- The message passed from master to slave and displayed on the 16*2 LCD.
Expected Outcomes:
- Students will get the Knowledge of I2C communication Protocol and the Arduino.
- The Hardware connection of all components used in this project.
- Displaying the message sent by master (Arduino) and received by the slave (16*2 LCD display).

Master code:
#include<LiquidCrystal.h>
int seconds = 0;
LiquidCrystal lcd(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(">> Master <<");
lcd.setCursor(0,1);
lcd.Print("SlaveVal: 99");
delay(1000);
}
Slave Code:
#include <LiquidCrystal.h>
int seconds = 0;
LiquidCrystal lcd(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);
}
