the voltage drop will be noticeable only at real close range
well it will work 'BUT' they will have very poor sensitivity
What I'm wanting to know is:Is it worth waiting/buying/harvesting proper receivers for the jobORWould it be efficient to try and do this with the reversed IR LED & LM324N [as I already have these on hand]It's my 1st attempt at making such a sensor, so was wanting some feedback/opinions before proceeding.
