I'm newbie to the world of arduino and environmental sensing. I have been searching for a while about how can I measure the heart pulse rate, I came through the following tutorial:
I have the following Arduino IR Receiver with metal shell module that I want to use as the previous tutorial suggesting, but, the IR receiver used in the tutorial has no metal shell, so, my question is if they are both functioning the same way?
Can I position my IR Receiver exactly as the one in the tutorial or do I need some workaround to reach my goal based on the fact that it has a metal shell?
Thanks in advance.
