I didn't have a schematic for it but it's quite simple - the LED just connects the three anodes to PORTB 1, 2 and 3 (each one through their own resistor of about 150 ohms) then the cathode of the led goes to ground. Thats it!

Looks simple to me, I would say use 100ohm resistors if your using a 3volt battery :)
