Graphing voltage using Arduino Problem
I'm trying to plot change in voltage though the use of Arduino. I pasted the provided code into Processing and when I run the code, the plotting window appears but it doesn't display anything. I do not get any sort of error message either. I'm trying to measure the conductivity in water and plot the change over time as the salinity increases and I'm just sticking a couple wires in the solution.
I'm on a Mac OS X Yosemite version 10.10

Have you verified something goes in the serial cable?
did you look here

PhiLho: I did a little fiddling after reading your comment and I was able to solve my problem. It was exactly as you said. I just needed to change which Serial Port Processing was reading from. I am a complete beginner at this and am learning bit by bit. Thanks for taking the time to comment
Well, I never used the Serial library, so it was a shot in the dark (but I have read lot of messages about this...).
