This project is my attempt to build LED color organ and VU meter both combined. The color of the LED depends on the frequency of the audio signal. The number of rows(i.e, arcs) depends on the amplitude of the input audio signal. This project uses Arduino pro mini,LM358 op-amp,mosfets which are easily accessible to everyone.
Watch the video to see the project in action. Use headphones for clarity. Please ignore my video making skills.”
