Password Door Lock System Using Pic

Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it.

Password door lock system using pic.

Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Now read the five digit password from the user. Atmega based garage door opening.

We are widely familiar with the password based e locks and might have installed in our house. The pic microocntroller used in this electronic door locks project is pic18f4520. Here at89c52 microcontroller is used and it is an 8 bit controller. After that microcontroller compares these arrays values with already stored valued of a default password.

You can also use other pic microcontrollers like pic16f877a etc. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. This controller requires a supply voltage of 5v dc. Electronic code lock system circuit design.

Like main password guests password public password to open the door closed the door. Also use p0 0 and p0 1 for motor driver. Also declare port2 to keypad. Password based door lock system algorithm.

This is an advanced door opening system compared to the above system. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2. Default password 1234 is stored in eeprom of pic microcontroller. If both the values are equal microcontroller opens the electronic lock.

You just need to change it in simulation and in code settings. I need to multiple password system door lock. After taking inputs from a user these inputs are stored in array. Electronic code locking system using pic 16f877 mircocontroller.

Then display the message enter password on lcd. 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.
