Password Door Lock System Using Pic

Atmega based garage door opening.

Password door lock system using pic.

You just need to change it in simulation and in code settings. You can use any other pic microcontroller if you want. If both the values are equal microcontroller opens the electronic lock. Also declare port2 to keypad.

After taking inputs from a user these inputs are stored in array. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Password based door lock system algorithm.

After that microcontroller compares these arrays values with already stored valued of a default password. 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. 2 or 3 different types of password. This is an advanced door opening system compared to the above system.

In this way a simple door lock system can be implemented with the use of a microcontroller. Then display the message enter password on lcd. Also use p0 0 and p0 1 for motor driver. Here at89c52 microcontroller is used and it is an 8 bit controller.

Electronic code lock system circuit design. I need to multiple password system door lock. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2. Default password 1234 is stored in eeprom of pic microcontroller.

Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. This controller requires a supply voltage of 5v dc. Like main password guests password public password to open the door closed the door.

We are widely familiar with the password based e locks and might have installed in our house. Electronic code locking system using pic 16f877 mircocontroller.
