I've been trying to make a multi-parameter biomedical system that displays various parameters like SpO2 percentage, Heart rate variability, etc., for which I want to use a red led and a photodiode in order to receive the reflected light from the skin. I would like to know whether this project is possible with a raspberry. The main reason I'm trying to do it with the raspberry pi is that the further part of my project contains a displaying part. It will be very easier for me if I use a Raspberry Pi as I am a bit familiar with using displays with Rpi's.
Please suggest me better ways to approach this project.
