Password Door Lock System Using Pic

Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

Password door lock system using pic.

Also use p0 0 and p0 1 for motor driver. This controller requires a supply voltage of 5v dc. Like main password guests password public password to open the door closed the door. Password based door lock system algorithm.

Electronic code locking system using pic 16f877 mircocontroller. Also declare port2 to keypad. Electronic code lock system circuit design. Atmega based garage door opening.

Here at89c52 microcontroller is used and it is an 8 bit controller. If both the values are equal microcontroller opens the electronic lock. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. 2 or 3 different types of password.

After taking inputs from a user these inputs are stored in array. The pic microocntroller used in this electronic door locks project is pic18f4520. Then display the message enter password on lcd. You can use any other pic microcontroller if you want.

Now read the five digit password from the user. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. 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.

I need to multiple password system door lock. This is an advanced door opening system compared to the above system. Default password 1234 is stored in eeprom of pic microcontroller. 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. In this way a simple door lock system can be implemented with the use of a microcontroller.
