animations of lights

[georges]

Hi!
I've just received my arduino and after a couple of tutorials, i tried to power up a line of 6 lights (one light at a time) from left to right 1-2-3-4-5-6. This went on fine, but now, I'd like to do the same, but starting with the second light, then the third, etc.
Wich means first 1-2-3-4-5-6, then 2-3-4-5-6, then 3-4-5-6, then 4-5-6, then 5-6, then 6 then go back to start of the program. I know i can do it like this :

int i;

for (i = 0; i< lineSize; i ++)
{
digitalWrite(pinArray*, HIGH);*

• delay(100);*
  _ digitalWrite(pinArray*, LOW);_
  _ }_
  _ for (i = 1; i< lineSize; i ++)_
  _ {_
  _ digitalWrite(pinArray, HIGH);
  delay(100);
  digitalWrite(pinArray, LOW);
  }
  for (i = 2; i< lineSize; i ++)
  {
  digitalWrite(pinArray, HIGH);
  delay(100);
  digitalWrite(pinArray, LOW);
  }*
  etc...
  But I'm looking for a simpler way. Do you know if it's possible and how?_

Hi Georges

something like that

int i; 
int j;
for (j=0; j<lineSize-1; j++) {
  for (i = j;  i< lineSize; i ++) 
  { 
    digitalWrite(pinArray[i], HIGH); 
    delay(100); 
    digitalWrite(pinArray[i], LOW); 
  }  
}
