Settings should be stored in EEPROM

A project log for Advanced Alarm Clock

We need to get up in the morning. This will wake us up no matter what.

There is EEPROM storage in both the RTC and the Arduino chip. Various settings should be stored in this memory that survives a power cycle.

Alarms can be read from their setting in the real time clock. When the alarm goes off it should set a pin high.

You only need a single alarm set, and the regular expressions to find the next time an alarm will fire.
