Need some help from the experts please.
I need to store a very long cell number between deep sleep intervals, but it seemsi will have to use a string to do it but are unsure how to do it.for ex 279999999999999999 - actual length of number.
I tried a few options but the number is longer than any integer type i could find and could not find an example where a string is used to read and write to and EEPROMaddress.
Thanks in advance
Already answered in previous post,
use the EEPROM class1
for example: save it in a char array:
char cellNumber = "27456985213"
EEPROM.put(0, cellNumber); // save it
EEPROM.get(0, cellNumber); // retrieve it
