Password Door Lock System Using Pic

Password based door lock system algorithm.

Password door lock system using pic.

This is an advanced door opening system compared to the above system. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. You can also use other pic microcontrollers like pic16f877a etc. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2.

This controller requires a supply voltage of 5v dc. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. Like main password guests password public password to open the door closed the door. I need to multiple password system door lock.

Electronic code lock system circuit design. Also use p0 0 and p0 1 for motor driver. The pic microocntroller used in this electronic door locks project is pic18f4520. You can use any other pic microcontroller if you want.

We are widely familiar with the password based e locks and might have installed in our house. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. Then display the message enter password on lcd. Default password 1234 is stored in eeprom of pic microcontroller.

Also declare port2 to keypad. After that microcontroller compares these arrays values with already stored valued of a default password. 2 or 3 different types of password. 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 using pic 16f877 mircocontroller. Here at89c52 microcontroller is used and it is an 8 bit controller. After taking inputs from a user these inputs are stored in array. If both the values are equal microcontroller opens the electronic lock.

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