/***************************************************************
To arduino uno attached neopixel ring via pin 6 with
 12 led write a code in such a way that first led blinkd once
  second twicce third trice and so on with random color
This code uses the Adafruit_NeoPixel library to control the
 NeoPixel ring. It sets the color of each LED to a random RGB 
 value, and then blinks the LED i+1 times (e.g., the first LED
  blinks once, the second LED blinks twice, etc.) using a loop. 
  The delay() function is used to control the duration of
 each blink.

The code now includes the necessary libraries for the LCD display
 (Wire.h and LiquidCrystal_I2C.h). Inside the setup() function,
  the LCD is initialized with the I2C address and dimensions,
   and the backlight is turned on.

Inside the loop, the code prints the serial messages as before,
 but now it also clears the LCD display using the lcd.clear()
    function and sets the cursor to the top left corner using
   lcd.setCursor(0, 0). The message is then printed on the 
   
  LCD using the lcd.print() function.
Note that the LCD display must be connected to the Arduino
 via I2C (pins A4 and A5 on the Uno). Also, make sure to adjust
  the contrast on the LCD using the potentiometer on the back 
  of the module, if necessary.
