Arduino Program to Print Hello World! on 16×2 Display

Arduino LCD "Hello World" Example

This Arduino program demonstrates how to use the LiquidCrystal_I2C library to control an LCD with an I2C interface. The program initializes the LCD, turns on the backlight, and displays the message "Hello World!" on the screen. This simple example is perfect for beginners who are learning to work with LCDs and the I2C communication protocol.

Components:

• Arduino Board: Any Arduino board like Uno, Mega, etc.
• I2C LCD: A 16x2 LCD with an I2C interface.

Libraries:

LiquidCrystal_I2C: This library simplifies the use of LCDs with an I2C interface. Ensure you have this library installed in your Arduino IDE.
