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, ...

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 ...
