I created 9 LEDs and light them and watch them rotate around.  I used pins 2 to 10.  Bottom LED is 10.  On the left from bottom to top 2 to 5.  On the right, top to bottom 6 to 9.  Green wires are grounds.  Red wires go the the LED pins. 

I used a while loop instead of the For loop that the video showed.  I prefer to use while loops in code. I set my timer to 800 and start thisPin at position 2.   When thisPin gets to 11, it resets to 2 to start over.


int timer = 800;
int thisPin = 2;
void setup() {
// put your setup code here, to run once:
for( int thisPin = 2; thisPin < 11; thisPin++)
pinMode(thisPin, OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
while ( thisPin < 12 ) {
if (thisPin == 11) {
thisPin = 2;
}
digitalWrite(thisPin, HIGH);
delay(timer);
digitalWrite(thisPin, LOW);
thisPin++;

}
}
