Hello, I am implementing a straightforward IR emitter / receiver pair for short range rangefinding and have come across some strange behaviour. I power the receiver from the board's 5V line, grounding it via a resistor to the board's GND, forming a voltage divider. I measure the voltage between the…

OK. Try a 47k in place of the 530k to +V and see what you get.
