2 or 3 different types of password.
Password door lock system using pic.
Password based door lock system algorithm.
Electronic code lock system circuit design.
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.
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.
Now read the five digit password from the user.
Here at89c52 microcontroller is used and it is an 8 bit controller.
Also use p0 0 and p0 1 for motor driver.
If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action.
Default password 1234 is stored in eeprom of pic microcontroller.
I need to multiple password system door lock.
Initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2.
In this way a simple door lock system can be implemented with the use of a microcontroller.
Electronic code locking system using pic 16f877 mircocontroller.
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.
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.
Also declare port2 to keypad.
Atmega based garage door opening.
You just need to change it in simulation and in code settings.
After that microcontroller compares these arrays values with already stored valued of a default password.
This is an advanced door opening system compared to the above system.
You can use any other pic microcontroller if you want.
The pic microocntroller used in this electronic door locks project is pic18f4520.
After taking inputs from a user these inputs are stored in array.
Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it.
