Pretty self explanatory. It's a $7.99 32x8 panels from sureelectronics. There's a huge thread somewhere about how to use them. I just wrote a simple PC program that does the FFT, and sends the data to Arduino, which displays it.



If anyone is interested, I'll upload my PC program somewhere.

Very interested, thank you.

thanks alot for the sureelectrics info, now i found alot of stuff i'll need to order

Thats sweet an LED panel equalizer! code would be nice  

[Reply #4 on:]

Yes code and other info would be brilliant!

Great project

Sorry for the late reply.

Here's the windows program that sends the spectrum to arduino:

And here is the arduino code:

Have fun!

Oh, forgot, you also need the "ht1632.h" from this thread:

Oh it's ok, most of us are very patient

A few days earlier: "That idiot hasn't posted up his damn code yet!"

lol

Yeah, like I said, very patient

Thanks a load anyway...

Very nice project.  Any chance you could also provide the source for the pc program that does the fft?  

[Reply #9 on:]

It's already posted. That one only does the FFT on one channel, I've made another version that displays stereo spectrum, I'll put that one up a bit later.

Oh oops, you mean the source code. It's programmed in Delphi 7, would that be Ok? I didn't write my own FFT algorithm, just used someone else's component.

[Reply #10 on:]

It's cool.  I'm mainly interested in how you manage to capture any sound being played on the system.  How do you manage that?  Are you using DirectSound?

[Reply #11 on:]

Can you still upload the source code, want to use it on an 16*24 matrix

[Reply #12 on:]

OK you can get the source code here: http://sites.google.com/site/iluvtocnc/LED_Spectrum.zip.

To build the project, you need Delphi 7.0, and VCL components Audio Lab, Signal Lab and Plot Lab, which are free on teh intarweb.

Hi zitron,

do u know how to use 2 of these panels together? I'm trying to extend the screen by using 2 of them.

[Reply #14 on:]

Uhm, I can't find a .pde anywhere?  :-? (The link links to the delphi-code..)

Could you upload that one again? (Pleeeaase )
