Title: Resistor question?
Post by: nico on July 31, 2009, 11:16:32 PM

what kind of resistor would i need if i buy this kind of LED?

would the 10 ohm work from radioshack?

R = (VS - VL) / I

R= resistor value
VS = supply voltage
VL = LED voltage
I = LED current (e.g. 20mA), this must be less than the maximum permitted

...id say try 390ohm, but because i am most likely wrong, wait for someone who knows better.

man i dont really get those calcualations, like sometimes it recommends lik 70 ohm and i can find them anywer...
i was thinking of using two of those. i want to know what kind of resistor i need.

oh, wait... psp battery uses 3.6V?
sorry, use 80 ohm resistor.

Rokujou is right use a 80ohm resistor
