Thanks for the quick replies. I have reviewed the data sheet (again) and I guess I just don't understand how to read these schematics, or at least not how to translate them to my breadboard. Please see the attached picture of my breadboard configured as I interpreted (apparently incorrectly) the non-parasitic schematic. If it's not clear, the resistor is connecting sensor pins 2 and 3.
If it helps, this is kind of how I am reading the schematic in English:
Connect sensor pin 1 to ground (Arduino GND pin on the side with the digital pins)
Connect sensor pin 2 to Arduino pin D3 (as specified in my sketch)
Connect sensor pin 2 to +5v (Arduino 5v pin) via 4.7k ohm resistor
Connect sensor pin 3 to +5v (Arduino 5v pin)
I imagine I am failing to understand the circuit(s) I have created on the board, even if I theoretically understand what the schematic is telling me to do.
Thanks again.
Andy
