ObstacIe avoidance / Infrared Sensor

Dear friends:
This a very newbie question, I'm trying to setup the Infrared sensor
decribed in Robotics 1.5 version PDF from Parallax, page 130 aprox.
I'm using a GP1U26X (40kz) as detector and a conventional infrared
LED emiter.
The circuit didn't work, the readings form the detector has no change
with or without the presence of the emiter LED, the reading from the
detector are very unstable, from 1 to 0, using the freqout command.
Maybe some of you have solved this problem or have a new and more
reliable circuit diagram.
I will appreciate any help in this issue, thanks in advance.
Bets regards
daniel

I think you might need to use a 10k ohm resistor as a pullup resistor from the
singnal wire to gnd from the det. this might help you out. i'll
