I was searching this forum for multiplexing LEDs and like this pattern a lot 
I'm installing navigation lights on a model aircraft.
Along with this flash pattern, I would also like to include an LED that gives the impression of a rotating beacon.
I have come up with the pattern as below based on PWM, but how would this be included that whilst the LEDs from the above pattern are doing there thing, the beacon is also running.
Thank you for any suggestions / help.
void Beacon()
{
 for(value = 1 ; value <= 30; value+=1) // fade in (from min to max)
 {
  analogWrite(5, value);   // sets the value (range from 0 to 255)
  delay(45);   // waits for 30 milli seconds to see the dimming effect
 }
 digitalWrite (5, HIGH);
 delay (70);
 for(value = 30; value >=1; value-=1) // fade out (from max to min)
 {
  analogWrite(5, value);
  delay(45);
 }
}
