This project is a revamp of an digital clock I've had for a while. I stopped using it because it had a tendency to "go too fast". After setting the clock it didn't take long before it was well into the future, which meant it showed the wrong time.
The problem I mentioned above is exactly what I want to fix in this project. I will build a new clock using the old one as a base and using components I have lying around. The "brain" (the clock) will be an Arduino since I don't have a RTC-chip lying around.
