Nick, Handy, Chris and Kevin’s Halloween creation

Content

  For our Halloween project we created a series of actions that are initiated with the push of a button by the audience, in hopes of getting candy. Basically, there is a sign that prompts the audience to push a button and then reach in a black pumpkin style container for candy. When a person pushes the button, a knife starts revolving over the basket(supposedly filled with candy) making it hard for him to reach in. If he manages to reach in, the knife stops revolving and  a gravestone that is behind the basket to the left revealing a scary face that rotates and opens and closes its skeleton hands and simultaneously sprays the victim with silly string. After he has endured all this frightening, there is a jar full of candy to the right of the scary face for him to enjoy. The sequence is completed when he pushes the button again to move the gravestone back and hide the scary face.

Structurally, when the EV3 touch sensor is pressed, a small motor rotates the knife. The hand in basket triggers an ultrasonic sensor located inside that prompts a large motor with wheels to move the gravestone. The scary face rotates using a small motor and the skeleton hands open and close using a series of gears connected to a large motor. The silly string is sprayed using a piece that is connected to a large motor and pushes down on the aerosol can. The sequence was programmed using LabView and we used two daisy chained EV3's.
