This is the Timer project kit from Kitronik. It uses a dual 555 timer. When you press the button it will start counting down and an LED will light up. Once the timer is finished the buzzer will make a sound. The duration of the timer and the buzzer can be adjusted using the potentiometers. This allows you to use the board as an egg alarm clock or a game timer. The maximum time is 200 seconds for counting down and 10 seconds for the buzzer.
