Step 4Customize and Win
Because I used a breadboard instead of a solid pcb you can simply change the behavior of the LED by changing the components around the NE555. In the default mode it fades in and out. Have a look at the images for some alternative circuits.
The first one is the simplest. Just light.
Picture #2 shows a circuit for a flashing LED. Change the value of C2 and R1 to adjust the speed.
Picture #3 shows 2 alternately flashing LEDs.
Go creative and share your circuits! (Contest)
I would be happy if you made the display and play around with the circuit. If you made your own circuit design, share it in the comments to get a 1 year pro membership. The only restriction: the circuit has to fit on a mini breadboard. Deadline is Jan. 31th 2012. So go creative and win!
