A photoresistor, as said before, is a **variable** resitor that changes depending on how much light hits it.

A resitor causes a **voltage drop** across its ends.

If we put 2 resistor in series, we get a **voltage divider**

This circuits divides the voltage depending on the resitor's value. If they are both equal, the voltage is divided in two halfs, 1/2 and 1/2. If one resistor has a value of (1/3)R and (2/3)R, the whole voltage gets divided in 1/3 and 2/3.

So, if we put a photoresistor in place of the first resitor, its **varying** resitance will lead to a **varying** voltage.

We just need to read the voltage value after the photoresistor.
