Keyestudio Passive Buzzer Alarm Module for Arduino

Overview

We can use Arduino to make many interactive works of which the most commonly used is acoustic-optic display. The circuit in this experiment can produce sound. Normally, the experiment is done with a buzzer or a speaker while buzzer is simpler and easier to use. The buzzer we introduced here is a passive buzzer. It cannot be actuated by itself, but by external pulse frequencies. Different frequencies produce different sounds. We can use Arduino to code the melody of a song, which is quite fun and simple.
