Fritzing BB View:
Total n00b: I am trying to layout my breadboard based this schematic, but I’m not sure if I’ve even come close. The LM34 in the graphic is actually a SS494B hall effect sensor. The schematic view in Fritzing is all sorts of wrong, and I assume the PCB view is as well.
Basically I wired all of this up, and I still get millivolts at what should be the Pin 7 to Arduino. I don’t seem to get any amplification at all at pin 1. My assumption was that i translated the Schematic to the BB completely wrong. How off am I?
