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.

This is a useful addition to my previous article “Arduino EEPROM”. The article is still available. I have provided a link here for convenience https://www.edn.com ...

Last week I spent most of my leisure time studying nonvolatile memory chips. The result was a better understanding of Arduino’s EEPROM. This might look like novice work, but I hope my thoughts will ...

Unluckly, only more expensive EPROM programmers can read them. I used an Arduino Duemilanove to dump 82S129 contents to PC for backup use. I used a breadboard to connect 82S129 pins to Arduino.
