Buzzer (small)

A small buzzer is an electronic component that produces a beeping or buzzing sound when electrical power is supplied to it. It can be connected to an Arduino or other microcontroller to provide sound alerts and notifications. Small buzzers are commonly used in projects such as security alarms, obstacle detection systems, traffic lights, timers, door alarms, and smart devices. They are simple to use and usually require only a small amount of electrical power.
