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.
The right glove is essential for this project. If you don't happen to have a candidate on hand, you can find Zombie gloves online.
