Hi I have interfaced my Arduino board to one of those wireless watch/heart rate monitors and am trying to produce a data logger that will log heart rate over something like a 12 hour period and be able to upload the data to a PC for analysis. I want to know what happens to my heart rate as I sleep …

That looks very interesting, thanks. I'll look out for your code.
