Password Door Lock System Using Pic

Also declare port2 to keypad.
Password door lock system using pic. Electronic code lock system circuit design. Electronic code locking system using pic 16f877 mircocontroller. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2. Now read the five digit password from the user.
We are widely familiar with the password based e locks and might have installed in our house. Atmega based garage door opening. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Then display the message enter password on lcd.
Also use p0 0 and p0 1 for motor driver. After taking inputs from a user these inputs are stored in array. After that microcontroller compares these arrays values with already stored valued of a default password. Password based door lock system algorithm.
You just need to change it in simulation and in code settings. 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. If both the values are equal microcontroller opens the electronic lock. Like main password guests password public password to open the door closed the door.
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. This is an advanced door opening system compared to the above system. This controller requires a supply voltage of 5v dc. 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. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. The pic microocntroller used in this electronic door locks project is pic18f4520. 2 or 3 different types of password.
You can use any other pic microcontroller if you want. In this way a simple door lock system can be implemented with the use of a microcontroller.
