hello with the node mcu it is possible

[@silenceandprogress]

Your work is very much interesting. I have tried to use MAX30100 with nodeMCU. Sensor is providing result while NodeMCU is connected with Oled also. But while i am trying to take the data to thingspeak or blynk app then MAX30100 showing zero data. MAX30100 not working then, not sensing beat. I am fighting to find out the solution. Will you please sir/any one help me to solve it. I will be grateful.

[@alphainferno7095]

I'm using M5stack version of max30100 and serial monitor shows first 6 characters of the first serial print message (Initial) only, when I disconnect the module then the Initializing message is completely shown and of course since the module is disconnected after a few seconds it shows as Failed. Any idea why this is the case with my build?

[@HowtoElectronics]

Hi Tarun, there are numerous reason for LED to not glow. May be you did some wrong connection. Check the supply at Vin pin using multimeter. Another problem can be with the sensor. You might need to do some modification in sensor. Check the website article, i have explained the method for fixing the issue.

[@shreyaspatel4412]

good way of explanation

[@alexsolo9189]

Does it will work same with arduino nano

[@amrapalibhagat9886]

Removing the resistors of max30100 is important

[@HowtoElectronics]

Its not important if you are cutting the tracking and soldering a jumper. In case if you don't want this, you have to remove all the 3 resistors and use external 4.7K resistors to SDA, SCL & INT pin. Kindly follow the instruction in the website article.

Why have you added a jumper(Brown wire) on MAX30100?

The MAX30100 board available in market has serious design problem. It will not work at any cost. So you need to make some modification in the board by cutting some track and adding the jumper. Check the link in the description for more details.
