Before capacitor power outage

Saving to EEPROM on power-out

An Arduino Uno that is driving no significant load takes around 45mA, so if your power supply is 9v and you detect power outage at 8v across the capacitor, with a 1000uF capacitor you have around 40ms before the voltage has dropped to 6v.
