Buzzer 5v - 6v Continues Beep Tone 12x9.5mm

The buzzer small is an audio signaling component used to produce beeps, alerts, tones, or simple sound feedback in electronics and robotics projects. It can be used with Arduino, ESP32, sensors, switches, alarm circuits, timers, and automation systems.

Buzzers are commonly used for warning indicators, button feedback, countdown timers, security alerts, obstacle notifications, and educational experiments. Depending on the buzzer type, it may produce a tone when powered directly or require a pulsed control signal from a microcontroller.

Its compact size and simple interface make it a practical sound-output component for prototypes and STEM projects.
