EEPROM

here quick question, what will happen to my Arduino board if i play with its EEPROM for 100000 times write and erase?

2

The bytes you write to 100000 times may fail and no longer be writable. I have heard they often last longer than that.

thank you... :slight_smile:
i dont unerstand eeprom.length concept,
what it really does?

4

again quick question

can anybody tell me if i used external eeprom to arduino,will it accept the all eeprom library code?

or anybody tell exact external eeprom model prefere to be used for arduino uno??

i need lot of memory or my project...please suggest cause i dont want to waste money buying wrong eeprom and i m new to this eeprom..

thank you

i need lot of memory or my project

What will you be using this memory for ? Could you perhaps use an SD card instead ?

6

if i used external eeprom to arduino,will it accept the all eeprom library code?

No, there are separate eeprom libraries for external eeproms. I prefer Jack Christensen's GitHub - JChristensen/extEEPROM: Arduino library to support external I2C EEPROMs.

The library for the internal eeprom will not work with them. If you have an RTC module it may have an external eeprom as part of the module, and you can experiment with using one.

Defining your memory requirements is the first thing to do.

to store so many of RFID tag in it...
10bits of hexadecimal value in it..

can you tell me which one is better to use??

tell me some reason too

8

to store so many of RFID tag in it...

How many?

thank you cattledog...sorry if its not ur real name... :slight_smile:

around thousand of tag in it..which is better to used eeprom or sd card?
