Circuit 4: Photo Resistor

In the previous circuit, you have learned how to use a potentiometer as
About this circuit:
an input device to control the LED's brightness.
In this circuit, you'll be using a photoresistor, which changes resistance
based on how much light the sensor receives.
Using this sensor you can make a simple night-light that turns on when
the room gets dark and turns off when it is bright.
