Let's see how a photoresistor react in light. Build the circuit above and notice how led brightness change. The resistance value becomes smaller when there is much light in the room. So in the dark the led remains off because the resistance has become very big. The Arduino will help us to reverse this situation, let's see how in next step.

Ambient Light Sensor Using Photo Resistor and LED Lights

A photoresistor (sometimes also known as a photocell, photodetector, or photoconductive cell) changes resistance depending on the amount of light it is exposed to. Use it as a variable component of a voltage divider circuit to build an analog light sensor. Buy a photoresistor from Sparkfun, Adafruit, or Newark.

LED Control with LDR (Photoresistor) and Arduino – Mert

A is a variable resistor. That is the simplest way to say it. Just imagine your potentiometer, you can control its resistance by turning the little knob and then analogRead it. The photoresistor on the other side, changes it resistance depending on the light intensity.
