Connect a LED and you should see it light up.

I can totally understand why you'd say "Screw it": I have made two circuits and neither one works for me. I have been trying to see if there is any way to verify the transformer is working - but since I am a novice, I don't know how to make sure it is working so I can rule that out as a problem. But, I won't give up - I'm still going to try again, and gain, and again :)
