# Crawling Animatronic Hand ## Overview This guide shows you how to make an creepy animatronic crawling hand. It uses a glove from a halloween costume, outfitted with a servo motor and a Circuit Playground Express. This hand is designed to pull itself along the floor slowly, waiting until it finds a cold, dark spot, at which point it will stop and wait until temperature and light increase.   ![](https://cdn-learn.adafruit.com/assets/assets/000/063/321/medium800thumb/robotics___cnc_IMG_8390.2018-10-09_17_22_14.jpg?1539126699) The right glove is essential for this project.
