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. Using a couple simple components, we'll light up a series of LEDs in order giving the illusion that the light is bouncing back and forth from side to side.

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.
14. Insert LEDs
Insert the LEDs as shown. The short legs of the LEDs plug in to the ground rail on the left side of the bread board.
15. Insert diodes
Insert a pair of 1N4001 diodes as shown. These diodes connect to the second LED from the top. Take note of the orientation of the white stripe on the body of the diodes. The polarity (which way the diode is plugged in) does matter.
16. Insert diodes
Insert a pair of 1N4001 diodes as shown. These diodes connect to the third LED from the top.
17. Insert diodes
Insert a pair of 1N4001 diodes as shown. These diodes connect to the fourth LED from the top.
18. Insert diodes
Insert a pair of 1N4001 diodes as shown. These diodes connect to the fifth LED from the top.
19. Connect 9V Battery
Connect a 9V battery as shown. The red wire is +9V, and the black wire is ground. Watch the LEDs light up in sequence and "bounce" back and forth.
