This is a very simple and very slow EEPROM programmer using an Arduino Nano based on the design from Ben Eater for his 8-bit computer project. The original design supports the AT28C16 EEPROM used that ...

In Arduino Uno, the EEPROM space can store up to 1024 bytes. A single byte can store 8 bits of information, and 8 bits can store a number from 0 to 255. In the Arduino IDE versions prior to 1.6.2 you ...

Meet the Arduino Compatible RFID Reader Module. It can hold card data for up to five cards, takes seconds to program, and holds card data in EEPROM memory, which means that the cards are saved ...

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 ...
