I need to multiple password system door lock.

Password door lock system using pic.

Now read the five digit password from the user. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Also use p0 0 and p0 1 for motor driver. Then display the message enter password on lcd.

In this way a simple door lock system can be implemented with the use of a microcontroller. You can use any other pic microcontroller if you want. 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 locking system design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and an lcd.

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. After taking inputs from a user these inputs are stored in array. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

You can also use other pic microcontrollers like pic16f877a etc. Electronic code locking system using pic 16f877 mircocontroller. This controller requires a supply voltage of 5v dc. Default password 1234 is stored in eeprom of pic microcontroller.

Atmega based garage door opening. 2 or 3 different types of password. After that microcontroller compares these arrays values with already stored valued of a default password. 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. 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. Also declare port2 to keypad.

Electronic code lock system circuit design. Here at89c52 microcontroller is used and it is an 8 bit controller.
