Communication with GUI, saving in an array and trying to make it permanent

Dear all, as part of my projcet, I have a GUI part were the user enters some DIGIT which are then saved in an array. Now when I switch the arduino of or reset, I loose this array = DIGIT saved.

Is there any way in which what the user enters keeps permanent??

Keeping the arduino on for ever is a last resort…


The on-chip EEPROM memory is a place you can write and read data on the run and it will survice power cycles and resets.


I just found that now lol. Tnx, a new look at the EEPROM it is :D
