Active Buzzer Module 3.3V–5V for Arduino & DIY Projects

Add audible alerts to your next electronics projectGive your project a clear sound notification with this Active Buzzer Module. Designed for alarms, status indications and user-interface feedback, it provides a simple way to add sound to Arduino-based builds, robotics experiments and DIY electronics.The built-in oscillator generates the buzzer tone, so you do not need to create an external audio-frequency signal. Switch the buzzer on and off through your controller to build alert patterns or notification beeps.Key Features 3.3V–5V DC operation: Suitable for low-voltage microcontroller projects. Active buzzer design: Built-in oscillation circuit for straightforward sound generation. Three-wire interface: Power, ground and control signal connections. Simple audible feedback: Useful for alarms, timers, button feedback and project status alerts. Maker-friendly module: Suitable for Arduino experiments, robotics and educational electronics. Technical Specifications Product type Active buzzer module Operating voltage 3.3V–5V DC Interface 3-wire: VCC (+), GND (−), signal (I/O) Sound generation Built-in oscillator; fixed-tone buzzer Connection GuideConnect the power pin to a suitable 3.3V–5V DC supply, GND to the controller ground, and the signal pin to a suitable digital control output. Check the markings on the actual module before wiring, as pin order and trigger behaviour can vary between versions. Disconnect power before changing connections.Applications DIY alarms and warning indicators Arduino and microcontroller learning projects Robotics status notifications Timers and button-feedback circuits School, college and maker prototypes Package Includes1 × Active Buzzer ModuleFrequently Asked QuestionsHow is an active buzzer different from a passive buzzer? An active buzzer includes its own oscillator to generate a tone. A passive buzzer requires an external frequency signal.Can it play different musical notes? This is a fixed-tone active buzzer, intended for beeps and alerts rather than variable-pitch melodies.Are a controller and connecting wires included? No. The package contains one active buzzer module only.
