/***************************************************************
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.
