I want to build a pulse-oximeter with gy max30100 sensor but when I connect all the pins in their place (VIN-5V / GND-GND / SCL-A5 / SDA-A4) nothing happens .I read on internet that this sensors are a little bit buggy .How can I solve this problem?
You need to write code, just plugging it in will do nothing. It's like jumping into a taxi, and saying nothing. What would the taxi do?
The code is uploaded ,don't worry about this ,but it just doesn't work like the LED is not lighting
After hooking the sensor up, did the I2C scanner detect the device?
Did you post a few images of your project all wired up, powered up and not working?
Did you post the code in code tags so we can see if its a code issue?
I have a project that does not work, what's wrong with it? <<<<< Curious, did you get any useful information from my statement to help you figure out the issue?
No.
Well this holds the same water:
So why don't you help us help you and post the code, a few images of the project and give the responders a break, after all they are only trying to help, for free.
I'm not worried at all. WHAT code did you upload? WHAT is your wiring? What Modle are you using? What logic level conversion are you using?
Which led? If it's the power led on the Arduino, you have connected things wrong or your sensor is faulty.
Further, which board are you using?
I've solved the problem and everything works fine with arduino nano and the code is this one `#include <Wire.h>
#include "MAX30100_PulseOximeter.h"
#include "Wire.h"
#include "Adafruit_GFX.h"
#include "OakOLED.h"
#define REPORTING_PERIOD_MS 1000
OakOLED oled;
PulseOximeter pox;
uint32_t tsLastReport = 0;

}`
but right now I'm waiting for an oled to add to this project ,I will send photo after all is finished
