That’s all you need to know in order to use and external serial EEPROM chip with your Arduino. As mentioned before, this is basically a dirty experiment with the 24C256 module. So, if you plan to use ...

Well, the EEPROM is the little space in chip memory where some data can be stored in the Arduino/ATmega328 even after power down. This seems fabulous! As another example of using EEPROM to help the ...

Since the ST24C04 512-byte device in question has an I 2 C bus it’s a straightforward add-on for an Arduino Mega, so we’re shown the wiring for which only a couple of pull-down resistors are ...

00:02:11: Arduino. 00:02:12: We're using an Arduino Uno for our programmer. 00:02:17: And you can see that we've got the address lines going to the 5.5 and then the data lines 00:02:22: going to the ...

Assuming the Arduino Nano clone isn’t using an amazingly high-quality EEPROM we can safely assume that most of us have nothing to worry about and our Arduinos will be functional for decades to come.
