Hey,
Ive just started to work with the Arduino board and Ive got a (silly) question!

I want to use more then 13 ledpins. For an example, how to do the "knight rider" with more then 13 leds?  :-/

Would be nice if someone could help me out!

Use something like the 74HC595, read this: http://www.arduino.cc/en/Tutorial/ShiftOut Or the max7219, use the search here on the forum to find some info.
