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:
Helpful tutorials:
- Flora main board
- Flora RGB Smart Neo Pixel
- Battery holder
- Piezo transducer
- JST extension cable

Insert the legs of the piezo into holes marked D9 (or any PWM-capable pin) and GND on the Flora. |
|
|
Solder the leads of the piezo and clip off the extra wire with flush snips. |

Peel off the adhesive protection and affix the metal bar from the magnetic pin back to your Flora. Now you can easily affix it to your clothes! Use a JST extension cable to lengthen your battery pack's wires so you can tuck the power pack in your pocket. |
