Password Door Lock System Using Pic

Now read the five digit password from the user.

Password door lock system using pic.

Default password 1234 is stored in eeprom of pic microcontroller. Atmega based garage door opening. After taking inputs from a user these inputs are stored in array. Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2.

2 or 3 different types of password. You can also use other pic microcontrollers like pic16f877a etc. This is an advanced door opening system compared to the above system. Password based door lock system algorithm.

If both the values are equal microcontroller opens the electronic lock. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. Like main password guests password public password to open the door closed the door. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action.

After that microcontroller compares these arrays values with already stored valued of a default password. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. 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. The pic microocntroller used in this electronic door locks project is pic18f4520.

Electronic code locking system using pic 16f877 mircocontroller. 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. You can use any other pic microcontroller if you want.

Electronic code lock system circuit design. Here at89c52 microcontroller is used and it is an 8 bit controller. Also declare port2 to keypad. This controller requires a supply voltage of 5v dc.

I need to multiple password system door lock. In this way a simple door lock system can be implemented with the use of a microcontroller.
