No, your wiring will not work.I was just worried that it would draw too much current? Now knowing that is is a receiver, is my wiring still correct?
and with regards to the op-amp... What EXACTLY is the 10M load resistor for? I thought the input bias current wouldn't need a current limiting resistor?
As with most circuits you grab off the web, the originator of the video is an inexperienced newbie who doesn't understand how to apply the subject IR receiver.
As I read Fig 4 in my post #18, above, if you put 5V across the receiver, it will source anywhere from 150uA (in the dark) to 20mA when maximally illuminated. I'm guessing that because he used a 10meg load resistor for the detector, he was concerned that he has only a tiny bit of illumination. E=IR, so if the receiver is putting out 150uA, the nominal voltage across the 10meg resistor would be 1.5V.
The opamp is configured as a voltage follower. However, if powered with 5V, the LM324 can only pull its output pin to about 3.5V, so the useful range of inputs to the Arduino's AD converter will be about 1.5V to 3.5V, a crappy design, with very little head-room.
