I'm going to install an IR obstacle sensor (like this one) to my Arduino nano.
I've found quite a few instructions on how to connect the sensor board to Arduino. Most of them connect IR VCC -> Arduino 5V, IR GND -> Arduino GND, and IR OUT -> any of the Arduino digital/analog input like this tutorial. But I also read this article on Instructables that connects the IR pins to A0, A1, and A2, which seems a lot cleaner. I know this should work but is there any thing that could go wrong in this approach if this device is supposed to work a week long uninterrupted?
