GitHub - Hzza3/Password-Based-Security-Door-Lock-using-Atmega16-microcontrollers: This is a Password Based Security Door Lock system based on 2 Atmega16 microcontrollers , one for user interfacing using LCD and Keypad and the other for storing data in the external 24c256 EEPROM , controlling the DC motor and the Buzzer used for the Alarm. The system uses UART for communication between the 2 microcontrollers and the Two Wire Interface (I2C) for communication between the microcontroller and the external EEPROM.
