Keypad Based Door Lock System Using Arduino

As thefts are increasing day by day security is becoming a major concern nowadays.

Keypad based door lock system using arduino.

Open your door with a special knock using arduino android phone and 1sheeld. Rfid and keypad door lock and alert system using arduino. The servo motor is used to push lock or pull unlock. Rfid and keypad based door lock using arduino.

The arduino board is connected to an lcd and a servo motor. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. First of all we will make the connection to the 4 4 keypad. Just thought of making a password based door lock system in which you can enter the password via the keypad.

It will open your door only when the right password is entered. Circuit diagram for arduino keypad door lock. You can simply copy paste the code using arduino ide. The simply compile it then finally upload it to the atmega328 microcontroller.

So a digital code lock can secure your home or locker easily. This is a simple arduino project. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. If you are using arduino mega then there is no need to use analog.

The complete circuit diagram for our arduino based digital keypad door lock project is shown below. In this post you are going to learn about how to build an rfid and keypad based door lock using arduino. To open the door the user will have to first scan the right tag and then he will have to enter the correct password. Unlock your door with a knock.

We used analog pins since we need more that 14 digitals pins for this project. First of all we start from the brain of this project which is the arduino uno board. A 4 4 or 4 3 keypad can be used to enter the desired password. The password based door lock system allows only authorized persons to access the restricted areas.

Digital door lock using arduino circuit diagram. The entire project is controlled by using the arduino. For connecting the keypad with the arduino we are using both analog and digital pins.
