A piezoelectric speaker is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and this motion is typically converted into audible sound using diaphragms and resonators. Compared to other speaker designs piezoelectric speakers are relatively easy to drive; for example they can be connected directly to TTL outputs, although more complex drivers can give greater sound intensity. Typically they operate well in the range of 1 - 5kHz and up to 100kHz in ultrasound applications.

Step 1: Material Preparation
For this tutorial, the items needed to run this project are:
- Arduino UnoUSB
- Male to male jumper
- Piezo buzzer
Step 2: Hardware Installation
The pin which have a + sign on the top is connected to one of the digital pin of the Arduino Uno
The other pin is connected to the GND pin of the Arduino UNO.
Step 3: Source Code
- Download the test code and open it by using Arduino software or IDE.
- Make sure that you have choose the right board and the corresponding port. (In this tutorial, Arduino Uno is used)
- Then, upload the test code into your Arduino Uno.
