Sorry to bring up an old thread, but I was doing something similar and i need your help. I have built a led light bar that has 40 leds and runs at 3.3v, that part i have sorted out. I also have a tip31c and i wanted to connect the light bar to my home theater system so that I could make the leds react to whatever I'm listening too. I need help on figuring out how to do this without damaging my a/v receiver. Also it would be cool if i could add something like pentiometer to the leds so that i can adjust their brightness say for example if I'm listening to music at low volume the lights will be very dim, but i can adjust their brightness with a pentiometer. Any help would be appreciated ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
