A piezo transducer can play a tone when supplied with a square wave signal. Using one of Flora's PWM pins, we can supply a square wave of varying frequency and duration to play melodies-- a wearable music machine!

For this quick project you'll need:

• Flora main board
• Flora RGB Smart Neo Pixel
• Battery holder
• Piezo transducer
• JST extension cable
• Magnetic pin back
  

As for tools, you'll need a USB cable, soldering iron and flush diagonal cutters.
