The little servo I am using is moving the arm when the power comes up in a rather uncontrollable fashion, until the pic is operational. With the linkage I am using, eventually it will cause some issues.

I am thinking about putting a 2n3904 on the ground leg of the servo and bring it up on a gpio, ensuring that the power is "off" until the pic is running and ready to go. Any ideas on this approach, or is there a better way to ensure the servo does not rotate at all until the pic is ready?
