Project 5: Buzzer clicking
Overview
In this project, we’ll bridge the gap between the digital world and the
analog world. We’ll be using a buzzer module that makes a small “click”
when you apply voltage to it (try it!).
Component Required:
 EASY plug control board*1
 EASY plug Passive Buzzer Module*1
 RJ11 cable*1
 USB cable*1
Component Introduction:
EASY plug Passive Buzzer Module
We can use Arduino to make many interactive works of which the most
commonly used is acoustic-optic display.
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. You can use Arduino to
code the melody of a song, which is quite fun and simple.
 Interface: Easy plug
 Working voltage: 3.3-5v
 Sensor type: digital
Connect It Up
Connect the EASY Plug passive buzzer module to control board using an
RJ11 cable.
