The Light Alarm is a circuit that sounds a buzzer when the light level falling on the circuit reaches a certain level. However, once triggered, the circuit will continue to beep even if the light falls below the trigger level and this can be useful in security situations where a burglars torch activates the alarm! So, how does this circuit work and what makes it better than other light detection circuits? Build this kit and find out!
