Discussion Board:
The 555 timer is a chip that is used to create a variety of pulses of different durations. The timer starts when voltage on pin 2 drops below 1/3 of the supply voltage. You can use a 555 timer to turn on a light for a certain amount of time, and you could also use a 555 timer for alarms and warning signals.
