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.

AIM:

• 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.

Design:

Prpgram:

//Master code

#include
#include
LiquidCrystal display(12,11,5,4,3,2);

void setup()
{
  display.begin(16,2);
  display.print("Hai slave");
  
  Wire.begin();
  Wire.requestFrom(2,10);
  Serial.begin(9600);
}

void loop()
{
  display.setCursor(0,1);
  while(Wire.available());
  {
    char c=Wire.read();
    display.print(c);
    Serial.print(c);
  }
}


-------------------------*************************------------------

//Slave code

#include
String a;
void setup()
{
  Wire.begin(2);
  Wire.onRequest(send);
  a="Hai master";
}

void send()
{
  Wire.print(a);
}

void loop()
{
 
}

Result:

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.

Summary:

• Here is the 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).
