The Alarm Challenge is to build an alarm device that will make noise and spin a servo motor.
The alarm will go off after a certain amount of time once a button is pressed or when its exposed to light
The alarm was built using the arduino board, a piezo, a motor,a button,a phototransitor, and other various parts.
