Password Based Door Locking System Using Atmega16

In this way a simple door lock system can be implemented with the use of a microcontroller.

Password based door locking system using atmega16.

The code for password based door lock security system using arduino keypad is given below. The program code for the opening or blocking of the system is found in case 16 key 16 of the run key function. You can simply copy paste the code using arduino ide. Atmega based garage door opening.

The simply compile it then finally upload it to the atmega328 microcontroller. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Password based door locking system design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and an lcd. Here at89c52 microcontroller is used and it is an 8 bit controller.

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. Password based keypad door lock using atmega16 simulation output of changing the password. Electronic code lock system circuit design. This controller requires a supply voltage of 5v dc.

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. Password based door locking system uses matrix keypad to enter the password this project is extended to operate on ir remote rc 604 in this project all required data is given circuit diagram c code pcb design and all related data this project is based on avr atmega8 microcontroller.
