That's what I used! Here, http://www.instructables.com/file/F9LKDFGGU7FXUMH, replace the motor with a relay in your head, that's the best I can do.
just in case I get wrapped up in this for a while
Just because something is published on the web doesn't mean it's error free or even correct.
alright guys im back, still having an issue, ill upload the fritzing diagram of how my circuit is connected, maybe this will clear it up
ok, so from what i gathered, hastily mind you, is that an external source was not needed as the rating is only 3v, which the arduino could provide easily. and from the schematics i saw, the source seemed like a bit of a black box that everybody just understood, clearly i didnt. is there a way to do this without an external power source? also i never claimed it to be a schematic, i used the word diagram appropriately and i think it offers a better view of the physical connections as it's clear im having a problem with the schematic view
Here's a really quick and dirty sketch of how it might look....
here's a new diagram.
Too quick, no base resistor shown.
could be a blown transistor, relay, connection etc
