What is Buzzer?
You must have heard a buzzing sound when you pressed the doorbell. Similarly, when the smoke is detected, the fire alarm goes off indicating that the building needs to be evacuated. This alert sound is created by the buzzer.
A buzzer is a component that produces a buzzing sound when an electric current passes through it. It is used in multiple applications like doorbells, alarm clocks, and security systems.
Buzzers are even used in the “Quiz game buzzer circuit”. You must have seen this type of buzzer in your school quiz competition or on “Kon Banega Crorepati”, where the participants have to press the buzzer quickly, so they would get a chance to answer.
