Design a device to record reaction time.

Participants will design, program, and test a "reaction time recorder" using the Pico Cricket microcontroller system. Reaction time is a measure of how quickly a person can respond to a given stimulus. It is one of the most common measures of neurological function and can be affected by many factors including exercise, sleep, drugs, and alcohol.

Visitors will use their invention to test their reaction time to visual and auditory stimuli as well as determine which body part responds most quickly to a given stimuli (i.e. dominant vs. non-dominant hand, hand vs. foot, thumb vs. second finger, etc.).
