resistors for lm386?..(tried many calculator and came up diff results.)

[akomismo01]

can someone calculate for me the right resistors?.. i'm confused on how ledcalculator.net, ledcalc.com and led-calculator.com came up with different answers.. i need the right one..

im having blue leds with

Voltage = 3.0-3.2
mA = 20

im trying to have 9 leds..

please help!

akomismo01 all you need is 191kohm and 30kohm resistors for the LM386.

i already have it.. i mean the resistor for the output of the amp... the ones that go into the leds... ive read somewhere that the output voltage of the amp is 5v..

If your doing sound reactive only you dont neet resistors at all. If your planning to witch between solid and sound reactive then youll need the resistor for the solid part only but other then that no you dont need resistors if your using sound reactive.

sorry for my noobish paint skill..

Yup you dont need it.
