Hello. I would like to make an electronic circuit which current or resistance would vary according to the intensity of infrared (i would probably use a potential divider). I've researched and apparently the photodiode is what i may use. However, I am unsure about whether the photodiode just do "switch on" and "switch off" of the current or does it have varying currents and resistances throughout quite a good range? Thank you very much!
