AT24C01 EEPROM Byte Read & Write with ATmega16 and LED Display

In this project, we will learn How to read and write a byte of data in AT24C01 EEPROM with AVR ATmega16 microcontroller and LED Display. Here, we will write a byte of data into the AT24C01 EEPROM memory and then we will read this one byte of data from the AT24C01 EEPROM memory and we will display the read value in a 1X8 LED array. AT24C01 has a storage capacity of 1Kbit(128 bytes). The 128 byte memory is divided into pages of 8 byte each. The data communication between AVR ATmega16 microcontroller and AT24C01 EEPROM takes place through TWI communication protocol. The AVR ATmega16 microcontroller will write a byte of data(in our case 0xAA) into the 0x00 memory location of AT24C01 EEPROM memory through TWI communication. Then it will read the one byte data from the 0x00 memory location of AT24C01 EEPROM memory through TWI communication and it will display the read value in the 1X8 LED array.
