I want to make a analog pov clock using arsuino. I need help with the code. I am using 3 74hc595 shift register to connect 24 led. Plz help with the code.

Thanx bill. I have seen that site but it didint have code for analog clock. Thanx a lot for your help. I jst needed a reference. Thanx for your code.. 
Hey bill i wanted code for analog clock not digital
You just need a reference, be it analog or digital clock is about the same for POV.
