The arduino and ESP8266 EEPROM library only provides functions to read and write one byte at a time from the internal EEPROM. Note that EEPROM has limited number of writes.
In this tutorial I will provide some functions to store string to EEPROM and Read back to String variable. String is basically character array terminated with null (0x00).

Basically String type variable in arduino is character array, Conversion of string to character array can be done using simple toCharArray() function. Getting string value in character array is useful when you want to break single string into parts or get part of string. Continue reading Arduino convert string to character array
