I am currently doing a project that involves making an infrared based heart rate meter. If anybody has done same thing then I would appreciate any info.
Specifically , I wanted to know abt suppose I have digital pulses(heart beats), then how do I count the heart rate. I know how to make a conventional frequency counter in which counting time is 1 sec, but here the counting time is 1 min, so if I do by that method then the problem is of generation of a pulse of less than 1 Hz freq.
