Hi. My alarm clock sketch stops running after five or six days, so I am presuming it is a memory problem. I have cut down the original code but still have a problem. I am using a Arduino Nano Board I have put up as much of the code as I can and attach a schematic.
This is my first project so if I am doing things wrong please let me know.
