my requirement is flashing of whole pattern
No you did not say that you just said
So please add the blink function in the code
That is what I added.
So exactly what do you want to blink and how?
The whole pattern or just the LEDs that are on?
If it is the whole pattern then use:-
for(int i = 0; i<8; i++){
led[i] ^= 1; // this will blink all the LEDs in the pattern
}
delay(300); // so you can see it.
