i'm using max30102 for my project to measure the person's heartbeat and oxygen level but the problem is after the wirings the led of the max30102 is not lighting here is our wirings:
vin to 5v
gnd to gnd
scl to A3
sda to A2
I2C SDA is usually A4 (remember "data" has four letters, so A4)
I2C SCL is usually A5 (remember "clock" has five letters, so A5)
Verify your MAX30102 uses 5v.
Are you using Arduino or ESPxx?
What is your microcontroller?
Using the "< code >" toolbar post your code.
Also post a schematic of your project
and if you feel like it, read it:

I have my majic looking glass looking at your unposted schematic and I see some parts missing and for sure it is miswired. Correct themistooks then run the I2C scanner and let us now what you get. If that does not work the sensor for sure will not work either. Get a copy of the arduino cookbook and skime the whole thing then read the sections perterenant to your project.
