Password Door Lock System Using Pic

Then display the message enter password on lcd.

Password door lock system using pic.

You can also use other pic microcontrollers like pic16f877a etc. We are widely familiar with the password based e locks and might have installed in our house. After taking inputs from a user these inputs are stored in array. Also use p0 0 and p0 1 for motor driver.

Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. 2 or 3 different types of password. 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.

If both the values are equal microcontroller opens the electronic lock. You can use any other pic microcontroller if you want. Atmega based garage door opening. 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 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 controller requires a supply voltage of 5v dc. Like main password guests password public password to open the door closed the door. Password based door lock system algorithm.

Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. This is an advanced door opening system compared to the above system. After that microcontroller compares these arrays values with already stored valued of a default password. Here at89c52 microcontroller is used and it is an 8 bit controller.

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. The pic microocntroller used in this electronic door locks project is pic18f4520. Default password 1234 is stored in eeprom of pic microcontroller.

You just need to change it in simulation and in code settings. Also declare port2 to keypad.
