Project 1 - Interfacing a 16*2 LCD with Arduino using I2C protocol
Interfacing a 16*2 LCD with Arduino using I2C protocol
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).

#include
LiquidCrystal display(12, 11, 5, 4, 3, 2);
void setup()
{
display.begin(16, 2);
display.print("hii slave ");
Wire.begin();
Wire.requestFrom(2,10);
Serial.begin(9600);
}
void loop()
{
display.setCursor(0, 1);
//display.clear();
//delay(1000);
while(Wire.available())
{
char c=Wire.read();
display.print(c);
Serial.print(c);
}
