The entire project is controlled by using the arduino.

Keypad based door lock system using arduino.

In this project we will learn how to make password based door lock security system using arduino keypad. A 4 4 or 4 3 keypad can be used to enter the desired password. It will open your door only when the right password is entered. Rfid and keypad door lock and alert system using arduino.

Circuit diagram for arduino keypad door lock. This is a simple arduino project. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. Open your door with a special knock using arduino android phone and 1sheeld.

As thefts are increasing day by day security is becoming a major concern nowadays. Rfid and keypad based door lock using arduino. Unlock your door with a knock. The password based door lock system allows only authorized persons to access the restricted areas.

You can simply copy paste the code using arduino ide. Digital door lock using arduino circuit diagram. Just thought of making a password based door lock system in which you can enter the password via the keypad. The arduino board is connected to an lcd and a servo motor.

In this post you are going to learn about how to build an rfid and keypad based door lock using arduino. If you are using arduino mega then there is no need to use analog. First of all we will make the connection to the 4 4 keypad. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.

The servo motor is used to push lock or pull unlock. So a digital code lock can secure your home or locker easily. First of all we start from the brain of this project which is the arduino uno board. To open the door the user will have to first scan the right tag and then he will have to enter the correct password.

For connecting the keypad with the arduino we are using both analog and digital pins. The code for password based door lock security system using arduino keypad is given below. On scanning the wrong tag or on entering the wrong password the system will deny access.
