Knight Rider Lights
By: kurt
The red flashing lights on the front of the car KITT in the popular Knight Rider series are an iconic visual effect. You can easily recreate this effect with this open source hardware project.

Steps
1. Insert 555 timer
Insert the 555 timer at the top of the breadboard. Make sure that the dimple on the top surface of the package is towards the top of the bread board.
3. Insert resistors
Insert two 1k resistors as shown. The first one is between pins 2 and 7 of the 555 timer, and the second one is between pin 7 and +9V.
4. Insert capacitor
Insert the 100uF capacitor as shown. The negative leg should be plugged into the ground rail on the left side of the bread board. The negative leg is indicated by a stripe or arrows on the cylinder.
