Password Door Lock System Using Pic

After that microcontroller compares these arrays values with already stored valued of a default password.

Password door lock system using pic.

Also use p0 0 and p0 1 for motor driver. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Default password 1234 is stored in eeprom of pic microcontroller. Atmega based garage door opening.

Like main password guests password public password to open the door closed the door. The pic microocntroller used in this electronic door locks project is pic18f4520. You can use any other pic microcontroller if you want. Also declare port2 to keypad.

You can also use other pic microcontrollers like pic16f877a etc. After taking inputs from a user these inputs are stored in array. Here at89c52 microcontroller is used and it is an 8 bit controller. In this way a simple door lock system can be implemented with the use of a microcontroller.

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. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2. Electronic code locking system using pic 16f877 mircocontroller.

This is an advanced door opening system compared to the above system. Then display the message enter password on lcd. 2 or 3 different types of password. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

If both the values are equal microcontroller opens the electronic lock. Electronic code lock system circuit design. We are widely familiar with the password based e locks and might have installed in our house. 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. Password based door lock system algorithm.
