An arduino project for my CSE 321 course, where an automatic light switch cover turns lights off in empty rooms/rooms where people are sleeping to save energy. This is code that operates a light switch cover designed following: http://www.instructables.com/id/Easy-Home-Automation-using-servo-switches/
The switch listens for noise in the room and upon not hearing noise in the room it waits for 30 minutes and then begins beeping. The user then has 1 minute to clap or press a button that cancels the light switch off sequence.
More information on this project can be found in the report PDF in the repository.
