Hello, So I am trying to develop a music visualizer in order to flash lights to music that is being played from Spotify. Ideally the colors change with the frequency. Currently I have the setup as shown by the attached diagram. I would like to not have to use a microphone or audio jack in order to pass the data to the arduino. It seems like I can use some sort of serial port in order to pass the data of the music through the usb and into the arduino to display on the LEDs. I am very confused in how to do this due to my limited experience with arduino. Could anybody help me with how to do this? Thank you in advance. Hopefully everything makes sense and don't hesitate to ask clarification questions if needed.

> It seems like I can use some sort of serial port in order to pass the data of the music through the usb and into the arduino to display on the LEDs. No sorry you can’t do this. The audio signal is not normally accessible in a digital form. And even if it were it would be too fast for a Uno. ---

What attached diagram is that then? Steve ---
