I found the problem. My 9V battery was low. I swapped it for a fresh one and that fixed it. I can duplicate the problem by swapping in the old one.

Now my next question. What should I use to power my ciruit? I'm using a 7805, and I'm driving a couple of servos, so I kill the 9V batteries quickly.

I looked at a few 9V AC to DC power supplies that I had lying around, but not enough amps I guess. The servos don't move like they should. A fresh 9V drives them at at first but run out quickly.
