I need help figuring out how to make LEDs light up to the sound of music but as standalone if possible. What I have so far is a Arduino Uno setup with 3 leds, jumper wires and resistors.
I was following a tutorial located here:
but getting to Step 3 number 9 they want me to use a mp3 file which is confusing (will it only play this song?) this part has got me sided tracked and confused wondering if this is the right tutorial to follow?
Im new to arduino and would like to have 3 LEDs light up to the sound of music (1 for bass, 1 treble, etc). Being so new I can't see how I do this as a standalone project (right now its connected to the computer through usb but later Id like to disconnect it and have it work with a 9V adapter I have).
I was assuming I would need some kind of speaker or something that could hear the sound to turn the lights on and off but Im doing my best to try and figure this out, any help would be greatly appreciated! I must just be thinking about it all wrong?
I suppose what you want to do is digitizing the sound, do some analysis/processing and output the result on the leds.
Take look here:coolarduino – Page 4
There is tons of stuff there related to this, but pretty advanced.
You can always make a QD solution by inputting the audio signal to an analog pin, reading it with analogRead() and outputting the value with analogWrite(). But i see not much point in that. That solution is not scalable at all and will lead you nowhere
I also found a Electret Microphone Amplifier so Im getting closer... I thought this stuff would be easy(boy was I wrong) and now I'll be happy to see one light dance to the sound of music.
I am making a project on LED flash to music using Arduino Uno board.

Now, my question is, How can I adjust the tune of lights or what program I should write for tunning.

You don't, you let the same program take in a different audio feed.
But another thing you don't do here is to hijack a 5 year old thread. If you want to know then start your own thread. Please read the forum rules here before posting again:- How to use this forum
What will Arduino bring to the project? Fancy blinking patterns that are triggered by the music? If it is only enough that the leds flash more or less to the music beat or intensity, I believe no digital logic is needed. You would need the audio line (like an AUX out or speaker out from an amplifier or a microphone with some amplifier circuit). Then a low pass filter, a middle pass filter (is it called a band filter?) and a high pass filter. The filter signals could be amplified, rectified, smoothed with a suitable capacitor and put into the leds. For achieving the fading leds, some circuit would still be needed. At this point, Arduino might still be a good choice: analogRead the rectified, smoothed signal, output a PWM signal (analogWrite) to the leds.
