Monitoring the output of a light-dependent resistor, or photoresistor, allows the Arduino to know how light or dark it is. When the light falls below a certain level, the Arduino turns on a couple of LEDs.
You can easily interface a liquid crystal display (LCD) with an Arduino to provide a user interface.
