This arduino unit uses the amount of light absorbed by blood to determine when the heart beats, and produces a graph that peaks when it does. The poster was also nice enough to post their code, and there'[s some more code over here that would be really useful to us (actually that's where I was linked from). Between the 2 we have everything we need to get his under way if we want to do it this way. At the end of the post their are some videos, final output's after about 50~55 seconds of the last video when the signal's been amplified. Enjoy :)

Does this Arduino Unit always need PC attached to it?
ReplyDeleteWe have to have several independent devices to be able to play with it.
So if we need a PC for each sensor, that would be very difficult.
