Lab 2: Analog In

The first setup consisted of a potentiometer being used to control the brightness of an LED



The potentiometer was then replaced with a photocell



Lastly, all the components were combined into a self contained unit which acts as an automatic candle. The LED grows brighter as the light in the room (amount of light received by the photocell) decreases.
