IR LED's, and the blood stream?
Hey I am in the process of trying out a circuit that will act as a portable pluse checker. I was hoping on using the IR LED's to reflect light from the clot of blood and if it bounces off (which it should) it will be picked up by a IR Detector. The whole project rests on the question if the IR light will bounce off the blood in my veins, and if it will be picked up by the detector. So i ask you....will this work?
Please keep in mind I am trying to keep the project simple, so no programming would be great!
