Hello,
This is my first post on the forums, and would like to say hello to everyone, and thank you in advance.
Now, onto the situation. I have no "professional" knowledge of electronics (diagram, components, etc). I merely tinker with them as a hobby. I have related small projects, like a simple 2-channel TIP31 led flasher; a Strobe light with variable speed; a portable audio mixer and a portable USB charger. Nothing real fancy. I would like tog et a bit fancier though.
I want to make a 5 band, "light organ." Where an output LED would light up depending on the frequency. For instance...
Audio input, 5 LED strings (not like an equalizer, all light up at presence of the freq. range), each LED string hooked up to light at (for example) Low, Low-Med, Med, Med-High, High Frequencies.
I have done some research. What I have found is that I will probably use Op-Amps to construct this. How ever, out of all my research I CANNOT find any information on Op-amps. I am looking for equations, and diagrams to determine the frequency of the audio and output.
I am going to base this project off of:

What I am looking for is some explanation as to what is going on here, where I can find further research on this idea, and any advice on how to go about this. (I do not want to copy this given circuit diagram, I want to remake it, while fully understanding what is going on here.)
