Alright, I am completely new to this forum so please excuse me if this question is obvious! Anyways, I'm building a proximity sensor system as a part of a school project and I am trying to use this IR sensor to get this whole thing to work:
Basically I need an LED to come on when a object reaches approximately 2ft away from the sensor. Looking at the output graph on the manual, we can see that at approx. 2ft (60cm), the output voltage will be around 1V.
So to sum the question up, how do I make a circuit which turns an LED on when the voltage only reaches 1V and up?
Ok, I've been researching this for an hour or so, and it sounds like something that would work - but having no experience whatsoever with using a comparator before, how would I get something like this to work?

^The circuit up there seems (key word:seems) like something that might work, but how would I incorporate an LED into this circuit?
