FOR implementation into variable name

Hi folks.

Just wondering how I integrate i into a variable name:

  for(int i = 1, i <= 10, i++) {
    digitalWrite(l + i, LOW);
    delay(d); 
    }

I'm sick of running through pin numbers LOL.

Cheers

Put the pin numbers in an array. Reference the array in the for loop:

const byte myLEDpins[] = {8, 4, 2, 9, 11, 12};
void loop()
{
   for(byte i=0; i<6; i++)
   {
      digitalWrite(myLEDpins[i], HIGH);
   }
}
