Hello everyone,
This is my first post in this forum, I hope that you can help me figure out the problem in the attached circuit.
The attached circuit is my attempt to make a Pulse Oximeter after modifying the original circuit from online. But it does not work. I have checked all the wiring but nothing.
How I can know if the Op-Amp or the photodiode are working correctly?
The power source of the circuit 3~3.3V.
Thank you all in advance
