IDeATe

Outcome

As you can see in the videos below, I was able to make the light blink on and off every 3 seconds, blink on and off 5 times then stop for 3 seconds, and have two LEDs alternate.

For this project, everything worked the first time. I liked being able to control what the lights did, and experimented with how short I could make the delay with the two LEDs and still perceive them flashing back and forth. That turned out to be 30 milliseconds.
