Buzzer is used to generate sound, beep or even melody of a song. It can be found in alarm devices, computers, timers and confirmation of user input such as a mouse click or keystroke. A piezo buzzer is not like a regular speaker that you might think of. It uses a material that actually changes shape when you apply electricity to it which in turn creates noise. The faster you bend the material, the higher the pitch of the noise that is produced.

A piezo buzzer is a small device that converts electrical signals into sound waves. Unlike traditional speakers, piezo buzzers operate on the piezoelectric effect. When a voltage is applied, the buzzer's piezoelectric crystal deforms, producing sound waves. This simplicity makes piezo buzzers cost-effective, lightweight, and ideal for applications where the space is limited.

Pulse Width Modulation (PWM) is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between ON and OFF. If you repeat this on/off pattern fast enough with a LED for example, the result is as if the signal is a steady voltage between 0 and VCC controlling the brightness of the LED.
