[@truetalonator]

thank you sir, you have been infinitely more useful than any of my TAs or profs in solving this issue

[@jungcookie7041]

Does it work for you

[@truetalonator]

@@jungcookie7041 ya totally fixed the issue

[@jungcookie7041]

@@truetalonator how did you do that

[@truetalonator]

@@jungcookie7041 scratched off the bad connection like he showed in the video using a really small flat-head screwdriver, then soldered a connection between that first resistor in the voltage divider and the pin using a small wire. His board had a nice pad connecting to the correct pin of the adc, but if yours is like mine amd didn't have that then you need to solder from the resistor directly to the adc pin mentioned in the video.

[@aldijbi18]

Thank you so much, it's work, i follow the cut method and jumper the internal resistor

[@codingclub557]

I followed this video as shown, but still not working MAX30100 was not found. Please check the wiring/power.

[@2kiranns]

Can you post a schematic of the external resistor added on Breadboard? The video was not very clear. Thanks in advance.

[@tobiadetula]

Would using a voltage divider on the SCL and SDA pins to essentially half the voltage of the I2C signal work?

After removing those 3 resistors and after making connection with external resistors ,after that also No red light on max30100 sensor .tried with two max30100s but pulse oximeter is failed. can you please help me out this connection ?

[@badrinarayans2290]

Sir i have followed the same procedure. As I have removed three resistors and i have used two 4.7k resistors for external connections. Even after all those efforts, it is showing "initializing pulse oximeter failed"

sir actually I have used esp32 with max30100

I bought max30102 (green color) I cut tracer as per first method you show. Still LED of sensor does not glow. I ran i2cdetect and it identifies my sensor at 57

So, change tga same i2c address in the code and try again.

Hi Guys We found that after following the steps ,It still dont work in this case try this. After some work around we found out that to use 5v for the max30100 sensor instead of 3.3V and it works. Hope this helps.
