I made this instructable for the Instructables Advent Calendar
. I hope it adds some fun to your waiting time for Christmas.
This display is highly customizable. I used a mini breadboard instead of a solid circuit board to give you the ability to customize the behavior of the LED by changing the components around the NE555. So this display is not only beautiful - its also educational. Learn about the timer IC NE555 by playing with your "Customizable Holiday Display"!
I added a small contest. Win a 1 year pro membership with your own circuit! See step 4 for more information.
