iron man motorized faceplate help


so i've been following this tutorial here and i (think) i assembled everything right, but when i connect my arduino uno and breadboard circuit assembly to my computer, the servo (i am only using one) makes 2 small turns, one in the opposite direction of the other. right then i found that to be strange because in the tutorial i'm following it says that when power is applied to the arduino no movement should occur. so i tried pressing the push button on the breadboard, and nothing happens. attached is a photo of my wiring (sorry about the quality, had to use my ipod). if you spot anything wrong, could you please tell me how to fix it? thanks!
