Password Based Door Lock System Using 8051 Microcontroller Program Code

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.

Password based door lock system using 8051 microcontroller program code.

These techniques are an integration of mechanical and electronic devices and highly intelligent. 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. User will enter the password using the keypad. Program of password based door locking system with 8051 circuit diagram of password based door locking system with 8051 protious simulation file.

All the processing s will be done by 8051 microcontroller. Various keys of keypad are as following i. 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.

It s a digital door lock system based on 8051 controller accept password from user to open the door connected with dc motor. Again if another person arrives it will ask to enter the password. Here at89c51 microcontroller is used and it is an 8 bit controller. The code for password based door lock security system using arduino keypad is given below.

You can simply copy paste the code using arduino ide. 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. How to design circuit of password based door lock system. For code and design log on to h.

The simply compile it then finally upload it to the atmega328 microcontroller. Door access system digital code lock keyless entry to home. This controller requires a supply voltage of 5v dc. It will provide keyless entry.

This can be used in banks. 0 to 9 ii.
