When assembled, the Moon Walker II uses a phototransistor to sense changes in light (such as turning on a lamp) and a condenser microphone to sense changes in sound (such as clapping). It converts those stimuli into electronic signals to power a motor, and walks forward for a preset time. The sensors can be adjusted for different sensitivity levels.
