Hi guys, I tried to build a park-aid and I am looking for the parts for Infra-red Led and Photo Diode.  I used a KIE-7305-1P and KIE-7304-1P.  Unfortunately, it doesn't work.  Can you guys please give me the part number for those diodes, thank you?  :-[

More KID-7404 is the Detector

I think you have 2 emitters in your circuit!
KIE means Knight Emitter
KID means Knight Detector
