Spider House

by Janeli Pelska & Tunahan Zilyas

Project Image	In Action

Arduino Spider House project features a container and a surprise spider. As your hand enters the container through a hole, covering the light sensor underneath it, a servo is triggered, lowering the spider to the hand inside the container.
