I always thought it would be cool to have a smart alarm clock, so I decided to build one for my kids rooms. I'm still working on this project, but I thought I would share it with the community.

I've used a few external libraries, and in some cases I had to modify them. Below are the links to the source, and I've attached my edited files to this project:
