Hello Everyone!
I've made a Spectrum Equalizer use 2 DMD with STM8S microcontroller.

Now I'm try to perform it with Arduino Uno, or Arduino Mega.
If you like it, please wait for a while. I will public it in this post when everything is ready.
So, please follow this post to get update.

Please enjoy it while waiting.

While wait you can subscribe my Youtube channel to get a lot of interesting electronics projects. Thanks you!

Here is video demo:

 

Nice

Where did you get the display?

Amazing you posted this because I was just trying to figure out how those Android app analyzers work.

How did you measure each frequency?

 

I use STM8S with FFT

I use FFT (Fast Fourier Transform) Algorithm to convert signals from the time domain to the frequency domain.

 

that's nice. the display must consume lots of current, given the large number of leds.

Yes! I must use power 5V-10A
