Product Information

Possible Applications Include:

The duration of both the delay and buzzer sound period can be determined by the student and are easily adjusted by PCB mounted potentiometers. The timer project uses a dual 555 timer, which once started by pressing the button illuminates an LED until the desired time out period has elapsed when a buzzer is sounded. This allows the board to be used for a variety of applications, such as an egg timer or a timer for a game (Max time period 200 seconds, max buzzer period 10 seconds).
