The purpose of this circuit is to detect changes in temperature to tell whether someone is lying. When my fingers touch the touchpads, the energy passes through my fingers, finishing the circuit and letting the speaker emit a loud squeal.

The purpose of this circuit was to test your reflexes. First, the two blue buttons were pushed down, then, the player tries to press the black button, and then as quickly as possible with the same finger, the blue button to the right of the black button. Pushing the black button will set off a strip of LEDs. The longer before the blue button is pushed, the more LEDs that light up.
