controlling LED's via USB?
I was thinking about making something similar to this
. I wanted to also have the 12 LED's (4 of each color). However, I also wanted to be able to control them from my computer, and possibly make them react to music. I'm not the most experienced with LED's, voltages, etc. etc. etc. I'm taking a digital electronics class, but we have been prototyping circuits on breadboards and building them with schematics software, so building a simple circuit wouldn't be too much of a problem. But, thats about all we've done. I don't have much experience writing code for anything, however, my friend is pretty decent with VB and vaguely able to code in either C or C## (forgot), so I could probably get him to help me with the coding. Can someone either point me to a website that would be helpful, or explain to me
A)How to make the circuit if I need to make one
B)How to connect it to my computer (I was thinking USB, but I'm not sure how I'd do it)
C)how to write a program to change colors, and possibly make it react to music
