ARDUINO HEART RATE SENSOR | PULSE OXIMETER | MAX30100

Project using blynk app with esp8266, oled, max30100, button, buzzer

Wonderful video but I have a problem, all is good my max30100 work, the red led turn on and the communication i2c works but in the monitor serial I don't see values only 0. Is a complex code but I tried only in the loop with millis but still now I can't see the correct values only 0 :c.

For me the max30100 pulseoximetee is not working
