For this assignment, I really wanted to explore the realm of music visualization. So I built a very simple a music visualizer that flashes an LED every time a new note occurs in a given piece of music. The music in the example is J.S. Bach’s Toccata and Fugue in D Minor, aka the classic Dracula song for a little Halloween flavor.
My initial prototype just included 1 LED blinking every time the note changed but my final product now has different LEDs for each given note.
The biggest challenge that I had while working on this assignment was that I has to learn how to incorporate an external servo driver for all the LEDs I needed. The reason that I needed to use this driver was because the ardiuno board itself did not support more than 12 pins so more has to be added.
