The Trick or Treat Box is a fun and interactive way to take trick-or-treating to the next level!

It is used for collecting candy from houses in the neighborhood on Halloween as a trick-or-treater. Rather than carrying around a pillowcase to hold all your candy, the Trick or Treat Box senses when anyone tries to put candy in your box, and immediately opens itself up with a Servo motor, revealing an opening to allow someone to put the candy inside.

The Trick or Treat Box’s red eyes, made of 10 millimeter LEDs, also light up when it feels (through an ultrasonic sensor) that someone is reaching over it to give it candy, since it is so excited to receive more! Upon receiving a piece of candy, the Trick or Treat Box will immediately close itself back up and its lights turn off, since it now is protecting the candy it received.
