/*******************************************************************************

to a arduino board 10 leds are connected to pin 3 to 12 and data pin
 of neopixle 24leds is connected to pin 2writea code to chase the leds
  from right to left then left to write delay 1000ms,also chase the all
   rgb leds clockwise and anticlockwise using random colors  repeat the  action

   The code uses the digitalWrite function to turn the individual LEDs on
    and off to create a chasing effect from right to left and left to right. 
    For the Neopixel strip,  the code uses the setPixelColor and show 
    functions to set the color of each pixel and display it on the strip.

   The random function is used to generate random values for the RGB values 
of the Neopixel strip. The delay of 100 milliseconds is used to slow down 
the chasing effect so it's easier to see.
