We will build a Weasley weather clock in this project using an Arduino microcontroller board and the Raspberry Pi. The Weasley Weather clock is inspired by the Weasley clock seen in the Harry Potter series of movies. A Weasley clock is used to identify the current location of a family member of the Weasleys (for example, work, school, and so on) and also the safety of the family member. Mrs. Molly Weasley (the matriarch of the Weasleys) used the Weasley clock to keep tabs on her family and this clock has had its variants over the years. This project happens to be one of them!

The Weasley weather clock is one that displays the current outdoor temperature and the forecast. It also warns us about impending dangers due to conditions such as tornadoes, blizzards, and so on.
