do you want to use the LM386 as a Sound Amplifier?

then do something like this, just put in a speker where the leds + and - goes..

and dont double post:

They can run the amount you are planning.

I think they can run way over 30...

i haven't tested myself, but that's from a trusted source ^^

How many leds are gonna go into this PSP!?  :whoosh:

lol, if you want other leds non sound reactive that diagram is correct, you may need to add the appropriate resistor for your LED's, or you can use a different power source.. Since leds normally run on about 2-3 V, i suggest using a different power source. Search on google for a site that calculates the amount of ohms needed to get the led on its right voltage.

Theres a 3.6V next to the plug where the charging port goes into the motherboard, you can user that

add a 100 ohm resistor between the 5V source and the leds, that should be enogh.  :tup:

if i wanted more than 2 sound reactive lights could i jus add more pos and neg leads from where the existing trigger leds are connecting to the lm386?......

Also can the lm386 do 2 functions at once?..... meaning can som lights attached to it b sound reactive and others not or will they all do the same thing
