part 4 - the code of the improved version
http://www.electronics-freak.com/fish-feeder-improved-code/
most important - this is basic code and simple.
It takes takes care of electricity power off! - meaning it will continue counting time from last time before power off, this is by burning in EEPROM (memory that is non violate) the hours and minutes
It will feed every 24 hours
Worked when I was in trip abroad and had no one to take care of my fishes
Enjoy,
Roee
