ok ccdust , now please tell me how you did it:

how did you connect the led to 3 pins? simple split? 2nd diode?
is it a hi-power led? if not then maybe a hi-power will work better

maybe you have a photo of your setup?

are you sensing a flash light??? it will  not work best!! leds sense their own bandwidth best!
so the best setup is 1 led as a light source and second as sensor

anyway good job

Hello,

  I've made it for one LED with Arduino without any anlog input, take a look at http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1146679536. Take care about pull-up.
Cordialement,
