Any Arduino experimenters here? I want to read an analogue (temperature reading from a 1-10v sensor) and a digital at fairly high frequency (~10ms intervals). If the digital is high I need to record the timestamp along with the analogue reading. When the digital goes low I then need to dump the recorded data to a CSV file and go back to reading the inputs waiting for the next time the input goes high. (Each period of logging would go into its own file and I can assume that there'll be time to do the logging etc before it goes high again.)
I figure that getting reliable uninterrupted readings will be easier with an Arduino than with (say) a Pi, but am I wrong to think that? Would the Arduino even do what I want? I assume I'd need to link it with (say) a Pi to do the actual writing to CSV file and sending it on (I haven't decided yet how but maybe FTP to somewhere or writing to a network share). I have zero experience with the Arduino but have been looking for a project to try one out and thought this might be it. That said, I'd rather use a Pi (w/ Raspbian) if it would be capable but it's not the actual rate that bothers me so much as the fact that some other O/S task might interrupt it and I'd miss samples.
