# Using Piezo Buzzers with WipperSnapper ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/117/322/medium800/adafruit_io_ksnip_20230104-161956.png?1672867356) Piezo buzzers are simple devices that can generate basic beeps and tones. They work by using a piezo crystal, a special material that changes shape when voltage is applied to it. If the crystal pushes against a diaphragm, like a tiny speaker cone, it can generate a pressure wave that the human ear picks up as sound. Simply change the frequency of the voltage sent to the piezo and it will start generating sounds by changing shape very quickly! This guide will explore how to generate tones with a piezo buzzer, code-free, with Adafruit IO WipperSnapper. It will also explore how to use a piezo buzzer as an alarm for a temperature sensor. ## What is WipperSnapper WipperSnapper is a firmware designed to turn any WiFi-capable board into an Internet-of-Things device without programming a single line of code. WipperSnapper connects to [Adafruit IO](https://io.adafruit.com/), a web platform designed ([by Adafruit!](https://www.adafruit.com/about)) to _display_, _respond_, and _interact_ with your project's data. Simply load the WipperSnapper firmware onto your board, add credentials, and plug it into power. Your board will automatically register itself with your Adafruit IO account. From there, you can add _components_ to your board such as buttons, switches, potentiometers, sensors, and more! Components are _dynamically _added to hardware, so you can immediately start interacting, logging, and streaming the data your projects produce without writing code. ## Parts ### Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM [Adafruit ESP32 Feather V2 - 8MB Flash + 2 MB PSRAM](https://www.adafruit.com/product/5400) One of our star Feathers is the [Adafruit HUZZAH32 ESP32 Feather](https://www.adafruit.com/product/3405) - with the fabulous ESP32 WROOM module on there, it makes quick work of WiFi and Bluetooth® projects that take advantage of Espressifs most popular chipset.
