Introduction: Arduino LED Music Spectrum
In this tutorial I'm going to show you how to make LED Spectrum with arduino.
First make this LED Matrix for Arduino. https://www.instructables.com/id/Arduino-LED-Scrolling-Text-Simple-Easy/
Use the Code on this Instructable below and upload it to arduino.(fixx_ftt files are the libraries)
Connect the Audio out of the music playing device to arduino Analog pin A0.
Make a comment thank you.

hey i have bit problem when i try upload code to arduino i get some error
F77HKA9I4SCTVX9.ino:1:21: error: fix_fft.h: No such file or directory
F77HKA9I4SCTVX9.ino: In function 'void loop()':
F77HKA9I4SCTVX9:27: error: 'fix_fft' was not declared in this scope

Hey, I've got the scrolling text working, added the fix_fft files through the libraries, but i'm getting a number of errors appearing for the cpp file:
C:\Users\Liam\Documents\Arduino\libraries\fix_fft\fix_fft.cpp:55:7: error: 'prog_int8_t' does not name a type
const prog_int8_t Sinewave[N_WAVE-N_WAVE/4] PROGMEM = {

Don't you need to amplify before connecting to arduino?

This works without any amplifier. I just connected this to my mobile phone headphone out and worked perfect.
