// pox.setIRLedCurrent(MAX30100_LED_CURR_7_6MA);
Find this line in your code and delete the //. The led should turn on.
If it doesn't, try replacing 7_6 with 11.

I try it wit GY-MAX30100 but my code didn't work. The error say that 'pulseoxymeter_t was not declared in this scope'. How could I repair it? I just copy your code. Thank you.
