heart rate monitor using IR emitter and detector. NEWBIE


I am pretty new at arduino and have limited programming knowledge. I have the circuitry of the detector set up and have found some code on line but it doesnt do what I want it to do. which is to have a separate led blinking at the same rate as my pulse. Im using the code at this link http://forum.arduino.cc/index.php?topic=94690.0

how would i modify this .. if i can get some help, that would e greatly appreciated.

at the same rate as

Do you mean in sync with the pulse rate, or not necessarily in sync, but just with the same period

I.e this sounds like a college project.

Is there a purpose to it.

Also did you try searching for Arduino Heart Rate Monitor It comes up with links like


Ie its been done before, so you can just copy their code and don't need to bother writing it yourself
