Arduino HeartBeat Monitor KY-039 lcd1602

Arduino HeartBeat Monitor
Hello again! Today i made a example for the KY-039.
I had a hard time getting this sensor to work, then i found out i am not the only one having a hard time with it.
Anyways i somehow got it to work with someone’s code So i did not wrote this one,
the code did not work at all at first but it seems it does work now.
Anyways IF someone creates something perfectly working with it then Please let me know.
