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 :)
Has anyone any experience or info they can point me at that will help me create some code that will both allow me to average the pulse by pulse heart rate readings I am receiving and store them away for later retrieval please? Maybe I can log average heart rate readings every 30 seconds so will end up with 1440 readings in a 12 hour period. Some sort of time stamp would be useful too so I can when the heart rate changes occur.
I have mega168 Arduinos.
