The Kitronik Timer Project Kit uses a dual 555 timer IC to create an adjustable timing circuit. Once started by pressing the button, an LED illuminates until the preset delay expires, after which a buzzer sounds for the set time period. Both delay and buzzer durations can be adjusted using potentiometers mounted on the PCB.

• Adjustable delay and buzzer sound with maximum time period of 200 seconds and buzzer time up to 10 seconds.
• Ideal for various applications including egg timers and game timers.

The kit includes components for self-assembly, making it suitable for educational use with detailed instructions and teaching resources provided.
