Arduino Tone Frequencies to Produce Specific Musical Notes

The arduino connected to a passive buzzer can actually be used to create simple music. In order to do this, we need to know the frequencies associated with specific notes. The code below can be used to directly write musical notes to the arduino tone command. This will be covered in an upcoming lesson. Enjoy!

 

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.
