WebPhotodiode Circuit When the photodiode is used in an external circuit, it is mostly used in reverse biased conditions. The anode is connected with the negative or ground and the … WebStep 2: IR Circuit 1 The first IR circuit will just show how the pair (IR LED & Photodiode) works. By using a transistor, we can turn dirty analogue from the photodiode into clean analogue which the output LED likes better. The circuit is very simple, all it needs is: Resistor: 2x 220ohm (or similar), 1x 10k
