Dear friends,

Finally I received my OSRAM SFH485P, but I´m confused. I can´t understand the datasheet ( http://www.farnell.com/datasheets/26627.pdf ).

Please help me guys. I would like to know the values I have to put in the wisard to calculate the resistors and the scheme (serial/paralell).

I´ll use a USB cable 5v, to a 3 points cap.

Forward Voltage (V): 1.5 or 3.0??
Forward Current (mA): 100???

Thanx!!!

Almost forget it: I´m using a wiimote.

I'm not expert as I am going to make my first LED setup too, but I would add 1.5V to LED wizard and something between 25-75 mA current.  The 100mA current is permited current  maximum.
The more, the brighter. In FAQ, they say 25 - 50 for webcam with IR filter removed and VIS filter added. 50-75 for unmoded webcam.

Hope that helps u.

Edit: look at http://forum.free-track.net/index.php?showtopic=1856&page=2
You can find this setup there with pictures and all data.
