# How this 9 LED Knight Rider Circuit Works Properly?

I have recently started working on 9 LED Knight Rider Circuit on a breadboard. All the connections have been done according to the circuit diagram given in this article. But I am having a problem with it - The light is running only one way instead of coming back and forth. Can anybody identify the problem and suggest me the modifications to be done to this circuit arrangement?

Sorry, but that's a truly atrocious schematic. I think it was badly copied from somewhere else. –  Spehro Pefhany May 6 at 7:16

Connect each LED with a series resistor from each output $Q_I$ to ground.
