Play The Simpsons theme song with Arduino and a buzzer
- - -
The Simpsons, that legendary animated series we all know and love, has become a cultural phenomenon. With its hilarious take on family life in Springfield, it's an absolute classic. We decided to have a bit of fun and recreate the show's iconic theme song using a piezo buzzer.

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.
