Help figuring out a spectrum analyzer project

Post by jaypuck »

I saw a beautiful little spectrum analyzer project in a video interview with LadyAda , its at about 30 seconds in the video. I emailed them (Adafruit) to ask if it was an available product and the response was it would be in the future. Fast forward to now and it apparently still isn't available since I can't find it, and I've decided I want to try to wing it.

It looks to me like its just an LED spectrum analyzer with some type of diffuser over it to soften the lighting effects? Any ideas what they're using for that?

I like the disappearing bars in the spectrum analyzer too, anyone know if that's a readily available piece of code?

Hunh.. I don't know that I've ever seen that one before.

That looks like a 16x32 RGB LED matrix behind a white acrylic diffuser, and probably controlled by a Nootropic matrix driver. We have those pieces combined as a kit here: https://www.adafruit.com/products/1073

I'm not sure about the code though.. we have several projects over in the Learning System that do FFTs and a couple of spectrum analyzers:

https://learn.adafruit.com/fft-fun-with ... transforms
https://learn.adafruit.com/led-ampli-tie/overview

but not that specific display.

I'll ask around and see if anyone knows where that went.

That was a project that ended up not being pursued. The code for it can be found in this thread:

Excellent, thank you both! This will be my first big Arduino project so that will help tons!
