KIT, TIMER BPSCA 2104 - HK01463 By KITRONIK
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.
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).
