READ / WRITE internally EEPROM of ARDUINO

Other Hardware Storage

Hi all,
is possible read and when I need write the eeprom inside arduino (not sd) ?

What I've in mind is:

  • turn on Arduino
  • check if on the memory is for example the number 1234 wrote
  • if no is wrote the code that I've put
  • if yes read the code and print it

I've looked into the forum but I didn't seen something like that ...

have nice a day,
Andrea

Did you look at the Learning page:

examples are right there on doing just that.

Thanks for the suggestions ... :roll_eyes: sorry but i lose this piece ... now i will look that :slight_smile:

thanks again ...I'll you know ... so due the fact the keypad is an digital input i hope there will be not a lot of difference :wink:

have nice day ,
Andrea
