Wiper Motor Tutorial 12vDC Parking Motors and PicoBoos

First and foremost, lets get the formalities out of the way. This tutorial is only about our PARKING MOTORS. And remember, whenever you’re working with any motor, make sure they’re completely disconnected so you don’t smash your widdle iddy biddy fingers. And please, never touch your tongue to any Halloween prop motor.

So why use a parking motor, you ask? Parking motors have an exact point where the shaft on the motor always returns to. In regards to orienting your prop, you can detach and attach the shaft arm depending on where you want your prop to stop.

How does this differ from regular motors? Well, normal motors have this thing called “drift”. Although the term is the same as the badass driving technique, the concept of drift in motors refers to the point after the motor is signaled to stop where it keeps going for just a little bit. They don’t stop instantly.

Imagine you have a Halloween skull mounted on a motor with the intention of it making spin one full revolution. With a normal motor, the skull will continue to drift past the signaled stopping point, leaving your bonehead sometimes facing the right way and sometimes facing the total opposite way. With a parking motor, the head will always return to the “parked” position. Ya dig it, daddy-o?

So now that you know that, on to the good stuff: using a parking motor with a prop controller. In this case, we’ll be using a Picoboo.┬áThe following diagram shows a PicoBoo being used to run the parking motor in one direction over to the park position.

As it says in the diagram, the process is fairly simple. Plug in your 12v 5a power supply, connect your positive (red) to your positive and your negative (black) into the negative. Connect the three wires into the relay output as shown. If you’d like the motor to work faster, use the blue wire instead of the green one.

For more customization of the wiper motor for your Halloween prop, we have the following graphic:

To start, tap the record button to begin programming. Just a note, this is the same with all Fright Ideas products.

For Clockwise Rotation:

  • Hold the “1” button and momentarily tap the “3” button. The motor will rotate until it reaches the park location and then will stop. Once that happens, let go of the “1” button.
  • To allow the motor to continue to rotate, hold “1” and “3” at the same time. When you’re ready to park, let go of “3”, wait until it parks, then let go of “1”.

For Counter-Clockwise Rotation:

  • Hold the “2” button in and tap the “3” button. The motor will rotate until it reaches the park location and then will stop. Let go of the “2” button.
  • To allow the motor to continue to rotate, hold “2” and “3” at the same time. When you’re ready to park, let go of “3”, wait until it parks, then let go of “2”.

When you’re done, hit the red record button again and your wiper motor program will be saved. It’s like a Halloween miracle, folks.

Now, if you want to have something with a little more customization with your motor, you can use a PicoBoo plus and add a speed controller to the mix. Connect it like so:
