![]() It displays the frequency components of the music. In the middle of thinking about what to build I found a plugin for my computer's keyboard (it has individually addressable LEDs in the keys) that transformed the keyboard into a music visualizer. ![]() My initial plan was to just remake my original underglow setup with a few strips of the WS2812b LEDs, however I figured that wouldn't take advantage of the LEDs being individually addressable. RGB data is passed from LED to LED, so the number of LEDs driven by one microprocessor can be huge. The LEDs typically come soldered to flexible strips which can be cut to length. I noticed over the last few years the WS2812b individually addressable RGB LED has become the go-to for cool LED projects. ![]() First thing I decided was to go digital instead of analog like the old visualizer (the use of a microprocessor lets me get a lot more creative without redesigning everything anytime I want to make a change).
