  Demonstrates the use of  an array to hold pin numbers
- in order to iterate over the pins in a sequence. 
+ in order to iterate over the pins in a sequence.
  Lights multiple LEDs in sequence, then in reverse.

  Unlike the For Loop tutorial, where the pins have to be
  contiguous, here the pins can be in any random order.
