Timed auto fish feeder

UPDATE:
I rewrite the code to use the built-in alarms of the RTC and then to put the Arduino to sleep when not in use.
If you use this code, please ensure you set the Event Hours and Event Minutes to the next Alarm time of your current time.
This will ensure the events and alarms are updated to set the RTC alarm to the next event.
I tried to run this from 2 18650 batteries, but unfortunately, they just about last 24 hours.
This is not enough :(.
The LCD is now blank unless you press the button where it will wake the device and display the time, next even and temp.
To use the new alarms and sleep, you will need to change the wiring:

Swap the button and IR sender wires so the button is now on Pin 3.
Wire the SQW on the RTC to PIN 2.
