Password Based Door Locking System Using Arduino Ppt

Password based door lock system using arduino simulino uno code include include.

Password based door locking system using arduino ppt.

This is a door lock security system made with arduino. Objective increase the security level to prevent an unauthorized unlocking of the door. Just thought of making a password based door lock system in which you can enter the password via the keypad. You can simply copy paste the code using arduino ide.

The entire project is controlled by using the arduino. This is a door lock security system made with arduino. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. A 4 4 or 4 3 keypad can be used to enter the desired password.

Connect your hardware as shown in circuit diagram above and now upload hex file generated from below code to the arduino uno board. Find this and other hardware projects on hackster io. The password based door lock system allows only authorized persons to access the restricted areas. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

Lock the door by using password. Electronic door look using arduino presented here is an electronic locking system in which arduino nano plays the role of the processing unit. The code for password based door lock security system using arduino keypad is given below. Since relay is mechanical switch between very high voltage controlled by 3 or 5 volt using npn transistor.

Give the flexibility to the user to change or reset the password in case the user forgets that combination. To give user more secure yet cost efficient way of door locking system. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.

The simply compile it then finally upload it to the atmega328 microcontroller. This circuit allows activation of an electronic door lock only on entering the correct password. Just thought of making a password based door lock system in which you can enter the password via the keypad.
