Password Door Lock System Using Pic

Also declare port2 to keypad.

Password door lock system using pic.

In this way a simple door lock system can be implemented with the use of a microcontroller. The pic microocntroller used in this electronic door locks project is pic18f4520. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. You just need to change it in simulation and in code settings.

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. Then display the message enter password on lcd. 2 or 3 different types of password.

This is an advanced door opening system compared to the above system. 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. If both the values are equal microcontroller opens the electronic lock.

I need to multiple password system door lock. 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. 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 the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. This controller requires a supply voltage of 5v dc. Electronic code lock system circuit design. Here at89c52 microcontroller is used and it is an 8 bit controller.

Default password 1234 is stored in eeprom of pic microcontroller. Atmega based garage door opening. Now read the five digit password from the user. You can use any other pic microcontroller if you want.

After taking inputs from a user these inputs are stored in array. Password based door lock system algorithm.
