Relay Transistor connection

view story

http://forum.allaboutcircuits.com – Hi guys! I had spend s couple of days trying to connect an npn transistor to a 12V relay. I am quite a newbie at this but I heard it is possible to use an npn transistor to translate a 5v source from a microcontroller to a 12V relay drive signal. If so is there a correct connection for this? I had tried to connect them with my limited knowledge but the relay contactor will not close. Any help is very much appreciated. :) Links for the pic layout: http://i41.tinypic.com/302309j.jpg (Embedded)
