Hello Friends, it is my first post and my English is not very good. I'm trying to connect a PulseSensor with my Arduino Nano v3.0, but measurements are incorrect. At the moment i'm using this library. I tried with 5v and 3.3v, but it doesn't work. I have also tried isolating the sensor, but it still does not work. Should I change anything in the library?
Thanks for your time, bye bye!
