The duration of both the delay and buzzer sound period can be determined by the student and are easily adjusted by PCB mounted potentiometers. 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).
