Arduino Controlled Ouija Board

If you're looking to chat with those on the "other side," might as well do it with Arduino!

Today we have a great project from SparkFun Engineer Joel - the Arduino-Controlled Ouija Board! Just in time for Halloween, this project combines some Actobotics parts, a couple of stepper motors, an Arduino dev board, some magnets (how do they work?!) and some other bits and pieces to create an X-Y table that is guaranteed to spook your friends. Check it out:

If you want to build your own, you can download the firmware here - and here is a wishlist of the parts involved:

  • Be careful! You may not believe in the demons you're conjuring up with your Ouija board, but you can bet your soul that they believe in you. Angels and Saints, pray for us.

  • a continuous rotation servo and a bit more code could make the planchette rotate as well as move for more lifelike movement.

    • Wow the pointy thing has a name? I had really planned on not learning anything today but I will accept this interesting occult tidbit.

    • Agreed. I've been mulling around a few ideas for the Z axis. Right now it can't quite reach all the points on the board.

      • Hi Joel, I don't suppose you've made one to sell or could make one to sell? - Failing this have you put together any fool-proof instructions>? Des

      • if you do implement a z-axis eventually, make sure it can spin exorbitantly fast as to be super scary like the demons are angry.

  • some more intel please got all the parts but the code is incomplete

  • someone got it worked out yet .i got all the parts but i cant get it to work just from the youtube clip some more intel please on this


  • Hello, Is there any step by step for dummies from assembly to programming ? I bought all parts but, without any plans it's really tough.


  • Anyone else price out the cart?

    One expensive Halloween prop.

  • Slides way too smoothly. Needs a little more jerkyness, like the planchette is fighting against the movement.

  • Ask the ouija board why all my caps keep leaking magic smoke!

    • Reversing electrolytic polarity angers the coulomb spirits. The capacitor sacrifices itself as penance.
