  • Just got the kit and built it, and am trying to write some code. I ran into a problem with the temperature sensor while trying to make sense of it’s output.
    Then I looked at the schematic. And then the data sheet of the LM335A. I don’t think it’s wired properly. The datasheet (and sparkfun page) seem to suggest putting a resistor between Vcc and the LM335, and using the voltage at the point between them as output. Pin 2 seems to be for calibrating the LM335 with a pot, not for reading from. Am I missing something obvious?

No public wish lists :(
