AirMelody is a special speaker which can visualize the music. In this project, we are trying to bring the visualization out of the screen and display it in the real world. We set up a series of glass tubes on a hand-made speaker, and used brushless fans to blow up the feathers inside the tubes. Through the controlling of Arduino, the speed of the fans could corresponded to the music. Therefore, the feathers will show the rhythm of the music in the air.
