I would like to ask. I want to make a counter, which even if it loose power, after I give power to it again, it will remember the int I want it to remember. Is there any way?
That should be all you need. Do note this memory has a fixed number of write cycles, so it is worth taking a little care to make sure you are not saving to it very rapidly.
Thank you. I am going to use it for fridge opening counter. WHen it opens, light shines and it saves into integer. Have a nice day
