Hey guys, I'm new here, and I'd like to ask you if anybody knows how to change the distance of detection with a IR Emitter, actually, I'd like to decrease it, I know that I have to place some resistors, so, If I change the voltage or the value of the resistor, this will have consequences in the distance detection, right, I'd like to know just an example or a quick schematic to see it. Thanks guys.
If the tracing paper isn't acceptable, look for a series resistor on the IR emitter and increase the value a good 10 times or so. Like if it's 4.7Ω, make it 47Ω.
