hey, sup.
i'm building a usb sensor bar w/ either 2 or 4 ir leds and my first question is if i should use 2 or 4... im not quite sure if 4 will be more powerful.
2nd question is if i should use a series setup or a parallel set up. Input would be apreciated!

1. Use four, why not?
2. Series.

If you use more than two, clump them together into two groups. The Wii was designed to use two lights (and many scripts also use two lights), so using any more or less than two can create problems. Clumping the lights together makes it seem (to the Wii Remote) as if there are only two lights.

ok, i bought some IR LEDs and... well, they dont tell u how many volts they need, so i dont know what resistor to get. Can somebody please tell me how to find this out? i tried going on the radio shack website. i found the product but all it supplies is that its 50mW...i need to find the voltage...
