Password Based Door Lock System Using 8051 Microcontroller Program Code

In this project i am going to design a simple automatic door lock system using 8051 89c51 89c52 microcontroller 16 2 lcd 4 4 numeric keypad and a digital lock.

Password based door lock system using 8051 microcontroller program code.

Password based door lock circuit design uses five major components a microcontroller a relay a dc motor a 4 3 matrix keypad and a lcd. These techniques are an integration of mechanical and electronic devices and highly intelligent. 0 to 9 ii. For code and design log on to h.

You can simply copy paste the code using arduino ide. User will enter the password using the keypad. The simply compile it then finally upload it to the atmega328 microcontroller. This digital door lock is simply a password based electronic code lock designed using 8051 micro controller a keypad and a 12 volt dc relay.

This project can be used in offices companies also at home. This can be used in banks. In this article we have designed a simple digital door lock using 8051 which can be used as a security checking system to limit access to an area room only for certain individuals with the password. Program of password based door locking system with 8051 circuit diagram of password based door locking system with 8051 protious simulation file.

Password based door lock system using 8051 microcontroller traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. It s a digital door lock system based on 8051 controller accept password from user to open the door connected with dc motor. Various keys of keypad are as following i. In our diy digital lock system 8051 89c51 89c52 is our intelligent unit.

This system demonstrates a password based door lock system using 8051 microcontroller wherein once the correct code or password is entered the door is opened and the concerned person is allowed access to the secured area. This controller requires a supply voltage of 5v dc. Here at89c51 microcontroller is used and it is an 8 bit controller. Door access system digital code lock keyless entry to home.

The code for password based door lock security system using arduino keypad is given below. It will provide keyless entry.
