http://www.sccs.swarthmore.edu/users/06/adem/engin/e72/lab7/ - A simple device that tracks a light source. Such a device can be used in satellites to keep the solar panels aligned with the sun, or in search and rescue robots that try to guide trapped people towards light. In order to implement the solar seeker we used two Cadmium Sulfide (CdS) photocells and a servo motor that rotated the photocells.

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1224541956/9 - Arduino solar tracker."Use two LDR's pointing in the same direction, but separated by a sheet of black cardboard/plastic/whatever. Unless they are facing the sun head on, one will show a very low value and one a very high as one is in the sun and the other is in the shade of the cardboard/plastic/whatever separator. If their values are not within a certain threshold of each other you tell the servo to run in the appropriate direction."
