Practice Exercise: 

Combining Sensors and Inputs 

In this exercise, I used a switch, photoresistor, and LED. The switch is controls the overall action of the LED light. LED and phtoresistor will only respond if the switch is switched on.

The scenario is for work lamp, which brightens up and dims down according to the existing light level in the room or daylight. But it will only work when the switch is on.
