Thanks for you answer.
I have tried that code, but all I get is data that is around 1000. That is, if I'm looking in the right place. It doesn't change when I place my finger on the sensor. I also tried to shield it from light, but no luck.
I couldn't find the answer in this thread: KY039 Arduino Heart rate code - Programming Questions - Arduino Forum
So, perhaps I might be setting it up wrong. Or do you think it has to do with something else?
