You installed the Centipede library from here: http://macetech.com/Centipede.zip
And ran the example code from here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1257672398/31#31
And nothing?
Do make sure you have a connection between pins 1 and 2 on the PWR jumper...
Are you saying that normal Arduino functions aren't working too?
What Arduino and IDE version are you using right now?
