Arduino LCD 16x2 Display

This project demonstrates how to interface a 16x2 LCD display with an Arduino to show messages and perform basic text operations such as scrolling and counting.

The LCD is connected to the Arduino, and messages are displayed and manipulated on the screen.

Components Needed

• Arduino UNO
• 16x2 LCD Display
• Jumper Wires
• Breadboard

Block Diagram

Hardware Wiring Explanation:

vss: Connect to ground (GND)

vdd: Connect to +5V

RW (Read/Write) GND

RS to pin 12

EN to pin 11

D4 to pin 2

D5 to pin 3

D6 to pin 4

D7 to pin 5

Power the Arduino

Connect the Arduino to your computer using a USB cable.

Software (Arduino IDE):

Open the Arduino IDE on your computer.

Write or paste the provided program into the IDE.

Select the correct board and port in the Arduino IDE under the Tools menu.

Upload the program to the Arduino.

Monitor the Output:

After uploading the program, the LCD will display "Circuit Digest!" followed by a scrolling message and a counting sequence from 0 to 9.

Project Operation

#include

LCD Initialization: LiquidCrystal lcd(12, 11, 5, 4, 3, 2); initializes the LCD with the pins connected to Arduino.

lcd.begin(16, 2); initializes the LCD to 16 columns and 2 rows.

lcd.print("Welcome to"); prints the message "Welcome to" on the first line.

lcd.setCursor(0, 1); moves the cursor to the beginning of the second line.

lcd.print("projectslearner"); prints "projectslearner" on the second line.
