If you love playing music and making electronics, why not combined these interests and create your own Arduino musical instrument? Instructables member audreyobscura has put together a fantastic set of instructions detailing how you can build your own xylophone.
The xylophone uses piezo sensors to detect when each note has been hit and then uses an Arduino Mega to turn this into a MIDI signal, allowing you to modify the music you make on your computer! If you are keen to get started on this project check out the following link.
If you're looking for a buzzer module to use in this project check out our sound and buzzer module:
Although you can use the sound and buzzer module to generate sounds, it can also be used as a knock-detector input to sense events and react to them. This means it is perfect for this project! For more information and to order, please visit the product page.
