Checking for Understanding

1. Design an alarm system that would alert you if somebody stepped on your front door mat. The warning should consist of a light turning on and a buzzer going off. (Note: you can buy a buzzer that will work with a single D-cell battery. You connect the buzzer like you connect a light bulb.) Describe how you alarm system works, and draw the electric circuit associated with it. Use D-cell batteries to power your system.
