Password Door Lock System Using Pic

Here at89c52 microcontroller is used and it is an 8 bit controller.

Password door lock system using pic.

Now read the five digit password from the user. Like main password guests password public password to open the door closed the door. Atmega based garage door opening. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

I need to multiple password system door lock. We are widely familiar with the password based e locks and might have installed in our house. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.

If both the values are equal microcontroller opens the electronic lock. This controller requires a supply voltage of 5v dc. In this way a simple door lock system can be implemented with the use of a microcontroller. 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. Password based door lock system algorithm. The pic microocntroller used in this electronic door locks project is pic18f4520. You just need to change it in simulation and in code settings.

You can also use other pic microcontrollers like pic16f877a etc. 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. 2 or 3 different types of password. Then display the message enter password on lcd.

After that microcontroller compares these arrays values with already stored valued of a default password. You can use any other pic microcontroller if you want. Default password 1234 is stored in eeprom of pic microcontroller. Electronic code lock system circuit design.

After taking inputs from a user these inputs are stored in array. This is an advanced door opening system compared to the above system.
