Basic Stamp Microprocessor
Average Rating:
Rate This Activity:
Intended Grade Level(s):
Learning Goal(s):

Students will synthesize the previous lesson for light metering and servo control to design a servo controlled by two photoresistors that will track a light source.

Lesson Number:
Other Subjects Covered:
Estimated Activity Length:
1 hour 40 min
Relevant Common Core Standard(s):

Students will learn how to program the Basic Stamp to use information from two photoresistors to point a servo at a light source. This will be the first degree of freedom for the flower head.
