Description:

Students will take the previous lesson and apply them in creating a light tracker with two degrees of freedom. The axis of rotation will be about the horizontal and vertical. Teams will have everything they need to make this build work. They have already created a tracker with one degree of freedom, so adding a second is a matter of replication. Students will use an additional servo circuit to add the next degree of freedom.
