Arduino Tutorial 24: Understanding Passive Buzzers

In this lesson we show you how to incorporate sound into your project using a passive buzzer. Passive Buzzers have the advantage that they are less expensive than active buzzers, and you can more precisely control the tone. This lesson will show you how to hook up the buzzer, and then how to code the arduino to produce different tones.

If you want to follow along at home, you can order the Arduino Kit we are using HERE.

Arduino Tutorial 23: Changing Tone of an Active Buzzer

In this lesson we show how you do have some ability to adjust the tone on the Active Buzzer to make a sound or alarm that is a little more interesting. If you want to make notes or play simple songs you should use the passive buzzer, but the active buzzer can be adjusted somewhat.

If you want to follow along at home, you can order the Arduino Kit we are using HERE.

The video above takes you through the hookup and the steps. Also, the code used in the example above is:

 

Arduino Tutorial 22: Understanding and Using Active Buzzers to Add Sound to Your Project

In this lesson we show you how to add sound to your Arduino project using a buzzer, The Elegoo Super Starter kit contains two buzzers, an active buzzer and a passive buzzer. The active buzzer is the easiest to use, as you just need to apply 5 volts to it to get it to go off. In this lesson we show you how simple it is to use the active buzzer with Arduino. In future lessons we will show you how to use the passive buzzer.

The advantage of the active buzzer is that it is easier to use. Just apply 5 volts, and it goes off. The advantage of the passive buzzer is that it is cheaper, and allows you more control of the tone, or pitch of the sound produced.  If you want to follow along at home, you can order the Arduino Kit we are using HERE.
