Password Based Door Lock System Using Pic16f877a

Digital door lock using pic16f877a with 16x2 lcd and keypad with dc motor.

Password based door lock system using pic16f877a.

Circuit breakers are electromechanical devices used in the power system to connect or disconnect the power flow at the generator substation or load location. The job of the mcu in this project is to receive signals from the input device keypad and take corresponding actions. Electronic lock takes inputs from the user with the help of 4x4 keypad. The password is entered by making use of a keypad.

The code for password based door lock security system using arduino keypad is given below. This is also such an electronic locking system in which pic16f887a microcontroller plays the role of the central processing unit. Circuit diagram of electronics lock is shown below. If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action.

This project is much similar to my previous one password based door locking system. Default password 1234 is stored in eeprom of pic microcontroller. Home microcontroller projects. The mcu is interfaced with a 4 4 matrix keypad and a 16 2 lcd to form the user interface.

Atmega based garage door opening. This system allows the user to unlock the device with a password. And then its asks to close the door by pressing digit one. This is an advanced door opening system compared to the above system.

If both strings matches then it will send signal to l293d ic and rotates motor in clock wise direction. The user can also set his password to ensure better protection. You can simply copy paste the code using arduino ide. 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. Programming the pic16f84a in c with mplab x duration. We are widely familiar with the password based e locks and might have installed in our house. Pic16f877a microcontroller reads these inputs and compared it with a already stored password.

This article describes the making of an electronic code lock using the 16f877a microcontroller. Razib shahadat 147 664 views. Same logic is used to rotate motor anticlockwise. The simply compile it then finally upload it to the atmega328 microcontroller.

Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Password based door lock system using arduino and keypad duration.
