Password Door Lock System Using Pic

If both the values are equal microcontroller opens the electronic lock.

Password door lock system using pic.

Like main password guests password public password to open the door closed the door. Atmega based garage door opening. Now read the five digit password from the user. You can also use other pic microcontrollers like pic16f877a etc.

Then display the message enter password on lcd. We are widely familiar with the password based e locks and might have installed in our house. Also use p0 0 and p0 1 for motor driver. I need to multiple password system door lock.

You just need to change it in simulation and in code settings. Here at89c52 microcontroller is used and it is an 8 bit controller. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. After taking inputs from a user these inputs are stored in array.

After that microcontroller compares these arrays values with already stored valued of a default password. Electronic code lock system circuit design. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. The pic microocntroller used in this electronic door locks project is pic18f4520.

Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Default password 1234 is stored in eeprom of pic microcontroller. 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.

2 or 3 different types of password. This controller requires a supply voltage of 5v dc. Electronic code locking system using pic 16f877 mircocontroller. 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. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2.
