I'm using a photodiode in parallel with a resistor in series with a LED to detect when light hits the photodiode.
The photodiode goes from 7kohms (with light) to 5Mohm (without light) and I'm using a resistor of 1.1Mohm.
I am planning on replacing the resistor (since it's big) with a transistor. If i remember my classes right, i should use a NMOS. any advice on the setup?
