Hey, I picked up some Super bright LED's from Radio Shack, the voltage says it goes up to 6 volts on them. I'd give you the stats, but I left them in the car... and my sister took it to the mall :(. My question is, with an USB mouse, can I just basically split the incoming voltage without use of a resistor?

I'll try to upload the LED stuff when (if) my sister gets back from the mall.

Thanks
Peace!

USB gives 5 volts so you can safely connect 6 volt led to it without the resistor. Because the supply is lower than that rated voltage it is not said that the led will be that bright or will it light up at all. Something you have to try and see.

That's correct! The USB can give 5 volts so it is safe to connect in 6-volt currency of electricity. If you are asking on the super bright LED, this depends on how strong the power it receives. If the power is high, the brightness of the led is good, but if the power is low, it would not be as bright as you expect.

I have some 20000 mcd lowvoltage leds, they only take 1.2V and 10mA.
Very bright light.
