A 5-volt passive buzzer is an electronic component that generates sound when an electrical signal is applied to it. It is called a “passive” buzzer because it does not have an internal oscillator and relies on an external oscillator to produce a sound.
The 5-volt passive buzzer has two pins for connecting it to a circuit board or other electronic device. One pin is connected to ground, and the other is connected to a digital output pin on a microcontroller or other device that can generate a signal.
When a signal is sent to the buzzer, it produces a sound with a frequency that depends on the signal’s frequency. The volume of the sound is determined by the amplitude of the signal.
Passive buzzers are widely used in various applications such as alarm systems, toys, and musical instruments. They are simple and easy to use, making them popular among hobbyists and electronics enthusiasts.
