This helps a lot in the project I'm currently working on. Thank you so much!

[@MrDrosini]

Amazing! I tested your code in Arduino Mega 2560 and it works flawless. Thank you very much!

Hello, I wanted to ask you if you have managed to calculate bpm and spo2 at the same time in the same code, if so, your advice would help me a lot.

[@jamesconway3900]

The linked code is goobered up at line 118-ish after this: double R = (sqrt(sumredrms) /
I would like to try this code if you could post an update. Thanks!

[@jamesconway3900]

Probably it was meant to be:
double R = (sqrt(sumredrms) / avered) / (sqrt(sumirrms) / aveir);

Tu salvou meu TCC. Manda o pix

[@calipsonikopony806]

you fixed it! lo arreglaste! ahora el código me funciona, ahora tengo que entenderlo para acoplarlo a mi proyecto. ¿como supiste completar el codigo? how did you figuredout the missing code?

[@mercedesmura8301]

i would like to know how did you connect the MAX to the ESP32, because in the video I’m not really able to see. If you could tell me, it would be great. Excellent video btw!

hello good work thanks.i have problem why the oxygen satiration is show in serial monitor is negative valeu like this Red: 108617,Infrared: 100617. Oxygen % = -5176478.00%

Can't see shit on the arduino log , its too white and washed out in the video

[@tinkerfoundry]

Will watch out for that next time...
