Circuit 1C: Photoresistor
Continuing on circuit 1B, where a potentiometer, which varies resistance based on the twisting of a knob. 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.
