Ok I will try to use the serial wires instead. Just so I'm clear, there is no serial port on the device, only 6 wires. I attached a picture of it and my pin reference sheet. In the user's guide, it does say that two of the wires are for analog output (one for fluorescence one for turbidity), but I'm going to give it a go with the wires hooked up to pins 0 and 1 and see if I can get anything.

Hello all,

I'm currently working on a project where I need to log data coming from a fluorometer using an Arduino Uno.
(link to spec sheet:

As for the actual logging, I plan to use the Adafruit shield.

What I need guidance on is simply how to get analog (or serial) data to the computer. I used the arduino analog read tutorial verbatim and hooked up the analog out pin on the fluorometer, and got rows of zeros in the serial monitor. I've tried changing the input pin, using the voltage display tutorial code, with no success. I can't figure out what I'm doing wrong.

If anyone has experience with this sort of project, I would like to hear your ideas.
