I have noticed that the diagram that FIRST has posted on the photo sensor is wrong if you go by the picture. If you follow were pin 1 goes it is correct but looking how the sensor ir positioned on diagram pin 1 and 3 are swapped. We caught this by looking at the datasheet from
http://www.kevin.org/frc/TSOP34840.pdf
I hope this will help any other teams that might be having some small problems with the IR sensors.
