I am creating a pond controller with an arduino nano That communicates over bluetooth to a mit app inventor app. I have the app send the start and stop times for the 4 electrical ports and then the arduino saves them to eeprom so if the power goes out it saves the programed times. Every loop i call EEPROM.update and give it the new data points, but when I read them back they are completely different numbers.

I made a output on the serial monitor to show what it gets from the phone and what it reads from eeprom.
Start1-12
Start1.1-1292
Start2-6
Start2.1-3334
Start3-18
Start3.1-6162
Start4-0
Start4.1-0
Start1-12
Start1.1-1292
Start2-6
Start2.1-3334
Start3-18
Start3.1-6162
Start4-0
Start4.1-0
Start1 is from phone and start1.1 is from the eeprom.
