Halloween is quickly approaching. And, what better way to learn robotics than to make an animated skull using Arduino. In this tutorial, I will walk you through how to make a moving and glowing skull to put on your doorstep and scare trick-or-treaters! Here's what it'll look like when it's finished! Ready to build yours?

Scare Trick-or-Treaters as They Walk By

The purpose of this device is to move and glow as a person walks by. To do this, we will retrofit a plastic skull with LEDs, a servo motor, and an ultrasonic sensor to develop our scary prototype. There are three main parts to this project:

  1. Adding glowing eyes with LEDs
  2. Rotating skull with a servo motor; and
  3. Motion detection with an ultrasonic sensor

I recommend following these parts in order. If you're more advanced, feel free to add in features to customize the look and reaction o…
