This project involved experimentation with the Makey Makey device. This device creates a low current circuit through any conductive or semi-conductive medium. When the circuit is closed, the Makey Makey device sends a key stroke to the computer. This allows the user to create interactions out of unconventional objects.
The first prototype was a simple arcade game. When players touch, the wings of the game character flap once. Maintaining flight requires continually clapping, tapping or high-fiving between the players.
The simplest, and potentially interesting, physical response I could think of was contraction / expansion. This is the behavior of a single muscle. I created a device with a single servo motor that flexed and extended against a cardboard spine. The result was a weirdly charming worm like creature that painstakingly inches across a surface with each flexion.
The players interact with the creature by placing opposing hands on conductive pads. The pads connect to a Makey Makey device which in turn connects to the base pin of a transistor. The transistor controls current to an input pin on an Arduino, triggering a servo on the creature.
