Password Door Lock System Using Pic

I need to multiple password system door lock.

Password door lock system using pic.

You just need to change it in simulation and in code settings. Electronic code lock system circuit design. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

In this way a simple door lock system can be implemented with the use of a microcontroller. Password based door lock system algorithm. 2 or 3 different types of password. Now read the five digit password from the user.

Then display the message enter password on lcd. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. 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. The pic microocntroller used in this electronic door locks project is pic18f4520. Default password 1234 is stored in eeprom of pic 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.

Like main password guests password public password to open the door closed the door. If both the values are equal microcontroller opens the electronic lock. Atmega based garage door opening. After that microcontroller compares these arrays values with already stored valued of a default password.

Also use p0 0 and p0 1 for motor driver. Here at89c52 microcontroller is used and it is an 8 bit controller. This is an advanced door opening system compared to the above system. You can also use other pic microcontrollers like pic16f877a etc.

You can use any other pic microcontroller if you want. This controller requires a supply voltage of 5v dc.
