Sparki has a buzzer that can make sounds.

How It Works

The buzzer on Sparki is a piezo electric buzzer. Piezo electric materials change their shape when electricity is applied to them: By turning voltage on and off to the piezoelectric material in the buzzer, the plate bends and moves the air back and forth:

This plate moving air back and forth compresses the air to make sound waves that you can hear:

Using the Part

With the basic Sparki code in place, you can make Sparki beep using this command:

sparki.beep();

SparkiDrduino already has code examples for you to use: File > Examples > Beep
