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! Check out the tutorial for this quick project over at the Adafruit Learning System, and watch the video on YouTube (please subscribe!) and Vimeo.
