Adding a Delay To a "Bin Loading System"

It looks to me as this example is simply showing how to blink an led, and this is not quite what I'm looking to accomplish, is there a way to manipulate this example to provide a pause between to digitalWrite functions?

It is not. It is showing how to do something - turn and LED on or off - and then later do something else - turn the LED off or on. You want to set a pin HIGH and then sometime later set another pin HIGH. That is NO different then some time later setting the same pin LOW, except that the pin number changes.
