When selecting a buzzer, consider its type (active/passive), operating voltage, current consumption, sound output level (dB), and physical size. Active buzzers have built-in oscillating circuits, producing a tone directly with DC voltage, while passive buzzers require an external oscillating signal to generate sound. Check your project's power supply and signal requirements to make the best choice.
