Can Anyone teach me how to make a Pulse Oximeter through Arduino in terms of Hardware and Coding ?
Would Appreciate if stuff is in Layman terms.

Have you used google, as this question is answered several times on the forum.
MODERATOR: Crossposts deleted (These waste time!!)
They all show the Result, none gives an exact way of working.
There is only one report but without code and hardware assembling.
