Arduino OLED Spectrum Analyzer

[@JB-20]

Seems didn't sync the music frequencies???

[@elecotechoz2455]

Yes.... I know its not the well version just the little Version for Visualization...... May be some "Analog Voltage Difference " or "Main Voltage" Fluctuation..... Use a Capacitor filter.....

Still works in 2024? I'm gotta made this and test it out :D

[@elecotechoz2455]

Yes it’s work always☺️

@@elecotechoz2455 I've try it, thank u so much, the code works for me as well

Very good project... 👍 how to make a stereo analizer

[@elecotechoz2455]

If you are talking about VU Meter then the video is already uploaded.

@@elecotechoz2455 no im asking for stereo audio spectrum analizer... Show both channels spectrum in one display.

Greetings from Poland. I'm on a similar project. The difference is a different audio source: DFPlayer. Everything looks ok music are played, but the graphic display after connecting it to the sound output (+) from DFPlayer gives no signs of life ... After disconnecting it from DFPlayer, the display responds to touch. Where is the problem?

[@elecotechoz2455]

I did not use DF Player Module before but I read some post that show DF Player only provides headphone quality sound means no amplification, you need a mini 4-5V amplifier module in the Output Section.... But if you test, check in low Volume first then you can rise the volume up for only testing purpose.....

No matter what I do ( already got the library sd1306 library ) I can't seem to get that nano_engine thing to show up

[@elecotechoz2455]

Check properly in the library..... Something wrong in your "nanoengine.c " Library

Hi, I am from Mumbai, is it possible to modify this code to Run on Nextion display, I need to get values for BAND 1, BAND2, ..... upto BAND10, so that I can use nextion progress bar (10nos) to show the dynamic value (Variable BAND), can you please help me ?

[@elecotechoz2455]

I did not use Nextion Display using Arduino any single time in my life but I know, it is possible using FFT Library and also you can modify it for more than 10 band frequencies

Hi, I'm from Indonesia, I like this project, but I want to ask, can the OLED display be combined with the menu selection display before entering the spectrum?

[@elecotechoz2455]

Yes its possible !

@@elecotechoz2455 ok, thanks, i will try it,, 🙏

Can this be done with a 128x92 display?

[@elecotechoz2455]

Nice Question...… But I don't know about this 128x92 display much more and never heard before.... So if you find any suitable library material and knowledge for this..... You have to change some function and code of FFT Library...…. May be It can work.....
