Password Door Lock System Using Pic

After taking inputs from a user these inputs are stored in array.

Password door lock system using pic.

If both the values are equal microcontroller opens the electronic lock. We are widely familiar with the password based e locks and might have installed in our house. Then display the message enter password on lcd. You just need to change it in simulation and in code settings.

Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2. I need to multiple password system door lock. 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.

Also use p0 0 and p0 1 for motor driver. After that microcontroller compares these arrays values with already stored valued of a default password. Electronic code locking system using pic 16f877 mircocontroller. You can also use other pic microcontrollers like pic16f877a etc.

If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. Electronic code lock system circuit design. Like main password guests password public password to open the door closed the door. You can use any other pic microcontroller if you want.

The pic microocntroller used in this electronic door locks project is pic18f4520. Also declare port2 to keypad. This controller requires a supply voltage of 5v dc. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.

This is an advanced door opening system compared to the above system. Password based door lock system algorithm. In this way a simple door lock system can be implemented with the use of a microcontroller. 2 or 3 different types of password.

Here at89c52 microcontroller is used and it is an 8 bit controller. Now read the five digit password from the user.
