I searched the site but I couldn't find a topic on this.
I see the voltage going through the IR emitter and I see the voltage go through a resister then either out the Vout or the IR detector to ground. If the detector does not see anything does its resistance go to infinity and the voltage go towards the Vout and if it does see IR its resistance drops and allows more current to flow through it and less through Vout? Or am I missing something that would explain it?
Strange, it's one of the circuits I have explained lots of time.
