How+do+we+go+about+the+actual+simulator+in+the+experiment?

How I think we go about the simulator is we put a piece of aluminum and two wires connected to each face of the aluminum foil and is connected to a raspberry pie with a little timing program. How we would measure there reaction time would be: we have a screen or a light that would turn on and then as soon as the light would turn on the person would have to push the brake pedal and then would also connect the circuit to time how much time they took to react to an image,light or sound. -Garrett
