Nothing really... Just hook the detector up to an input and the led up to power with a resistor and its all good.
Just make sure the wavelengths of the emitters and detectors and the same

great thanks smash
making another order soon(hopfully)

Hi,
If you don't use anything but a couple of resistors, the range will be really short.
Here's a couple of pages you might wanna read:
