Project 1 - 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).
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);
