Arduino Playground I2. CEEPROMI got my hands on an AT2. C2. 56 2. 56 kbit 3. EEPROM. I found no library for it, so I created a small sketch with few functions to show how the i. Because this chip is I2. C, it only uses the analog pins 4 5 SDA and SCL, and of course the power 5. V and GND. Connect as follows. Arduino analog pin 4 to EEPROM pin 5. Arduino analog pin 5 to EEPROM pin 6. Arduino 5. V to EEPROM pin 8. Arduino GND to EEPROM pin 1,2,3,4. Be sure to leave pin 7 of the EEPROM open or tie it to GND otherwise the EEPROM will be write protected.
