This project is like a special calculator that tells you how many hours of sunshine there will be today. To make it work right, you need to tell it where you are by giving it your latitude. Latitude is a way to measure how far north or south you are from the equator, which is an imaginary line that circles the Earth. The North Pole is really far north of the equator, so its latitude is 90°. The equator is right in the middle, so its latitude is 0°.
