Ok, here's the theory. I'm working on a series of sculptures made from materials which are translucent or transudant. LEDs will be mounted inside and be driven by sounds in the environment (mic) or connected to an audio device and illuminate the work from within, showing it's inner colors, which are quite different from their exterior colors. They look totally different from natural light, and subsequently become different sculptures........
Also, I want the sound input to filter the signal into frequency bands, so that the LEDs light up at different intervals and at different locations in the work. So basically, I'm sculpting the sound, light and matter.....LOL.
So, can someone help me with designing a filter circuit? I can find a lot of eq circuits but something always seems to come up to confuse me or throw a wrench into things. Things like of course the circuit ends all mixed, instead of having separate leads to connect LEDs to, and no clear way of keeping them separate, etc..,
I have found one circuit that did it all, but I couldn't get it to work. It was a three band which drove 3 10 led bar graphs. I wonder if it might have been the transistors orientation. But then I looked into ICs.......
So, if I can get help with a simple three band, I can go to five and seven on my own. So from an input source plug, into three bands and out to separate LEDs, would be great.
I've also looked at filter calculators, but not sure if I know how to connect things from there. Like if I use an op amp for a band pass filter, can the output drive an LED, or do I need a PNP and resistor first?
Also, is there an easy to use designer, simulator and analyzer? I'd like to be able to change the component values and see the change in frequency response, in addition to being able to see if it's gonna work......LOL.
TIA
