WebbPhotodiode Definition: Photodiode is a two terminal electronic device which, when exposed to light the current starts flowing in the diode. It is operated in reverse biased mode only. It converts light energy into electrical energy. WebbPhotodiodes are easy. You connect them reversed to the +5V (cathode!) and the anode to a resistor to ground. If light falls on the diode it will cause a current through the resistor, which will cause a voltage across it. So you can choose the sensitivity by choosing a …
