pomt on gpt    write a  code to display poem about ten lines on a lcd2004 i2c connected to arduino uno

by arvind patil 20/08/23

This Arduino sketch uses the "Wire.h" and "LiquidCrystal_I2C.h" libraries to control 
an LCD display with I2C communication. It initializes a 20x4 character LCD display and displays 
a poem in segments on the LCD, each segment with a delay of 3 seconds. The code demonstrates the 
following steps:

The necessary libraries, Wire.h and LiquidCrystal_I2C.h, are included.

An instance of the LiquidCrystal_I2C class, named "lcd," is created with the I2C
 address 0x27 and dimensions of 20 columns and 4 rows.

In the "setup()" function:

The LCD is initialized using the "init()" method.
The backlight of the LCD is turned on using "backlight()".
The display is cleared.
The poem is displayed on the LCD in segments with delays:

Each segment consists of a few lines of text printed using "lcd.print()" 
and positioned with "lcd.setCursor()".
After displaying each segment, there is a delay of 3 seconds using "delay(3000)".
The "loop()" function is empty for this example.

The code demonstrates how to display different lines of text on the LCD and 
control the display timing using delays.
 It uses the LiquidCrystal_I2C library to facilitate communication with the LCD2004 display.
