This is how I wired the Arduino up with the shift registers and the EEPROM chip. It looks very confusing but most of that is just the data and address buses, which follow a very logical pin mapping. I ...

This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar parallel EEPROMs using an Arduino. Since the Arduino doesn’t have enough pins to directly control all of the address, ...

Every time one of us flashes an Arduino’s internal memory, a nagging thought in the backs of our minds reminds us that, although everything in life is impermanent, nonvolatile re-writable memory is ...

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 ...

Learn how to initialize and manage EEPROM settings on Arduino to store data like user preferences, calibration values, or configuration settings — even after power off! This trick helps make your ...
