I had the same problem the first few times I breadboarded any circuit using my microcontroller. I am not sure if our problems are alike, but I remember that I was not pushing on the microcontroller hard enough (so it wasn't fully connected on the breadboard). Because of that, the blinking lights were dim and sometimes really wacky.
Again, just taking a crack at it. Doesn't hurt to push the microcontroller in more. By the way, don't take a hammer and whack it in place-- I mean gently press it so it is in more .
