The Robodo Active Buzzer Module (3.3–5V) is a compact and easy-to-use sound output device for alerts, alarms, feedback tones, and audio signaling in robotics, embedded systems, and DIY electronics projects. Unlike passive buzzers that require external frequency generation, this active buzzer module includes an internal oscillator, allowing it to produce a continuous tone simply by applying a logic HIGH signal — which makes it ideal for quick, simple audio signaling with minimal coding or hardware setup.

Operating over a wide voltage range of 3.3V to 5V, this buzzer integrates seamlessly with popular development platforms like Arduino, Raspberry Pi (via logic-level control), ARM, AVR, PIC, 8051, and other microcontrollers. Connection is straightforward using the standard three-pin interface: VCC, GND, and Signal. Simply send a digital HIGH to the signal pin to trigger the buzzer, making it perfect for alarms, status notifications, user feedback, or beeps in control systems.

The board-mounted design and breadboard compatibility allow easy prototyping without needing additional components. The module’s low current consumption makes it suitable for battery-powered systems or low-power applications. It also responds quickly to digital triggers, ensuring responsive audio feedback when your system needs to alert the user.

Common uses include robot collision alerts, keypad feedback tones, alarm systems, timer beeps, UI interaction sounds, and event notifications in microcontroller-based projects. With its simple interface and reliable performance, the Robodo Active Buzzer Module is a must-have for building intuitive, responsive electronic systems.
