    Aim:

    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).

    Solutions:

     Master code:

    #include<LiquidCrystal.h>                        //Library for LCD display function

    LiquidCrystal lcd(12, 11, 5, 4, 3, 2);         //Define LCD Module Pins (RS,EN,D4,D5,D6,D7)

    int val1=A4; 

    int val2=A5;

    void setup()

    {

    lccd.begin(16,2);

    }

    void loop()

    {

    lcd.setCursor(0,0);                     //Sets Cursor at line one of LCD

    lcd.print(">> Master <<");          //Prints >> Master << at LCD

    lcd.setCursor(0,1);                     //Sets Cursor at line two of LCD

    lcd.Print("SlaveVal: 99");            //Prints SlaveVal: in LCD

    LCD

    delay(1000);

    }

    Slave Code:

    #include <LiquidCrystal.h>                     //Library for LCD Display Function

    LiquidCrystal lcd(12, 11, 5, 4, 3, 2);        //Define LCD

    Module Pins(RS,EN,D4,D5,D6,D7)

    int val1=A4;

    int val2=A5;

    void setup()

    {

    lcd.begin(16,2);

    }

    void loop()

    {

    lcd.setCursor(0,0);                             //Sets Cursor at line one of LCD

    lcd.print(">> Slave <<");                  //Prints >> Slave << at LCD

    lcd.setCursor?(0,1);                         // Sets Cursor ar line two of LCD

    lcd.print("MasterVal: 100");              //Prints MasterVal: in LCD

    delay(1000);

    }
