Infared sensors????

hey i have a question, is the infared receiver suppose to come in the kit or are you suppose to build your own, and if so where do you get parts and instructions for it??? and if it was suppose to come in the kit how many others didn’t get it.

the receiver is a three pin device - looks like a square with a lens on one side - you should have gotten 4 in the KOP . you connect it directly to a PWM cable, but you have to cross the wires over - check the documents section of - there is a whole page of links to files on the IR under ‘beacon’ in the list of docs.
