Hi,
I am looking to build a basic spectrum analyzer (if that is what you would call it) out of some LED lights for a car stereo.
Basically, I want about 8 - 10 bars (for different frequency bands), and I want them to jump up and down to the music, giving it a direct feed off of the car stereo head unit.
Looking for advice on components, any schematics that I may be able to use for the various parts (I figure I will need to build several cheap bandpass filters for each of the frequency bands, or use some sort of multi-band filter that I might find in a basic cheap equilizer circuit or something like that.
Still trying to get some ideas.
