Arduino Uno LCD 16x4 Display

This project demonstrates how to use a 16x4 LCD display with an Arduino Uno to output text. The LiquidCrystal library is used to interface with the LCD, and a simple example prints "Hello, World!" on the display.

Components Needed

• Arduino UNO
• 16x4 LCD Display
• Potentiometer (typically 10kΩ)
• Jumper Wires
• Breadboard

Block Diagram

Hardware Wiring Explanation:

Connect the LCD Display to Arduino Uno:

Adjust the contrast using the potentiometer if needed.

Connect the LCD display and potentiometer to the Arduino Uno as described in the circuit setup section.

Software (Arduino IDE):

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Uno.

Verify if the LCD display shows "Hello, World!" as expected.

Applications

Notes

Ensure the LCD pins are correctly connected to the Arduino Uno and powered.

Adjust the contrast using the potentiometer to ensure text visibility on the LCD.

Modify the code to display custom messages or incorporate other features supported by the LiquidCrystal library.
