DIGITAL CODE LOCK USING AT89C2051 PDF

The digital code lock system with LCD using microcontrollers is a password-based system. This project can be used as a security checking system to stop access to a room only for unauthorized persons with the password. So this project can be named with a wide range of names such as a digital combination lock, a digital security code lock, a password security system, an electronic code lock , a digital code lock. People name this type of a security system with various names, although all of them mean to make a password-based security system with a different microcontroller with some extra features like automatic door open or lock, GSM-based SMS alert , sound alarm, etc.

The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple. The input is taken from a 4x3 Keypad please see the schematic for more information and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock.

For demonstration i have connected an LED to that pin. If user has to do setup his own code, then he has to enter "" and press ' '. After this.. Entering master lock, user can enter the new 5 digit code for the lock and press ' ' to save it. Numeric keys are used for entering numbers. H - LCD function prototypes and other declerations Lock.

Digital Code Lock with LCD and Keypad using AT89C2051 (Electronics Project)

Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. Even now, there are Digital locks which can be operated using our smart phones, means no more need to keep different keys, just one smart phone can operate all the locks, this concept is based on Internet of Things. In this project, we have explained a simple Electronic code lock using Microcontorller , which can only be unlocked by a predefined code, if we enter the wrong code, the system alerts by siren the buzzer. We have already created a Digital lock using Arduino. Keypad is used for inserting password into the microcontroller. Buzzer is used for indication of wrong password and LCD is used for displaying status or messages on it.
