Windsheild motor zervo pulse

I am making a Rocking, singing, Drunken, Pistol Shooting, Pirate. I use a windshield motor to rocks him from side to side. But at times I want to be able to stop him for awhile when he is straight up not leaning on the side. I was going to use an IR TX and RX board. But I knew the Windshield motor when in the car is stopped when they are all the way down. So I opened the motor up and had a look at the insides. There is a plate inside with rings with different lengths the one in the center is just a little stub that will make continuity for a short time as the motor rotates. That can be used to stop the motor at that position.
