I'm a completely newbie about Ardunio but I find this discussion really interesting...
I'm working in a lab on a study about the corrosion of pipes and I want to build a data logger with Arduino.
Why? Because it's cheaper, smaller, more flexible (and more fun to do) than the data logger I'm using.
My measurement are just made with an electrode (reference electrode) every x second (i.e. every 5 seconds or 1 minute or whatever i set) then logged in a csv file. The measurement are mV.
The csv is really simple: Elapsed time - mV from Electr. 1 - mV from Electr. 2 - .... - mV from Electr. X.
something like this:

Is it possible to do??? And how?? (like for example, to change the frequency of data logging).
