I'm creating a project where the motors have to be triggered by a photodiode. A light provides a steady stream of current to the photodiode and when that incident light is scattered, the motors move. But in reverse bias a photodiode needs to have a dark environment to provide 'infinite resistance' and only allows current to pass if light is shone upon it, opposite of what I need accomplished. I don't have the schematics of the apparatus yet. Does forward bias of a phototdiode perform the task of a reverse bias photiodiode oppositely?
