This tutorial will teach you how to construct a pair of Arduino-powered “voodoo twin dolls” that reflect actions done to one doll on its twin. For instance, if you touch Doll A’s left hand, Doll B’s left hand will light up. If you pick up Doll B, Doll A will vibrate, and so on.
These dolls will be set up with a modified Arduino code and be wifi enabled. This way, they can communicate in different rooms, different buildings, and even different states.
