ok the lm3915 sounds like something useful and i have searched google(about 14 hrs total) for a rather simple circuit that just involves the voltage regulator, power source, resistors, and leds. Many circuits are very terrible and dont involve a current limiting resistor or dont involve the audio jack (i want to hook it up to my computer).
I will make it simple and see if someone can arrange them in a way that makes sense to me.
Parts: lm3915, resistors of some value,8 - 3v blue leds(preferrebly 4 for left speaker and 4 for right but if it makes it complicated this can be omitted), 12v wall phone charger, and audio jack. (idk if there is a transistor needed b/c of the lm3915)
I just need a simple schematic made from this, im sorry if this is a nuisance and i know there have been threads on this before but b/c I am a newbie to this i cant really modify it to my liking without understanding what the voltage regulators do. if someone could just draw me a circuit in paint or something like that with the parts i will give you 1,000 personal respect points over what you already are at.
EDIT: leds in series or parallel? audioguru you have stated that series is better but wont that drive all of the voltage through the first led and just burn em out?
also i have read every thread on here after hours of searching and none exactly fit what I am trying to do
lastly, no one post in here just saying "color organ" or "let me google it for you", if it were that easy i would have found what i wanted by now
EDIT2: i do not want a VU meter, just blink to light with fading in and out, but maybe the lm3915 does that
another 1,000 personal respect points for the pain for the 2 edits
