This is simple matrix alarm clock. It can be used as casual home gadget. I design it as I don't find any existing project with simple schematic and software. I think this project will be very easy for replication and custom modification. You can see all information about this project on GitHub: <a href="https://github.com/vikonix/O-Clock">https://github.com/vikonix/O-Clock</a>
