In this post you are going to learn about how to build an rfid and keypad based door lock using arduino.
Keypad based door lock system using arduino.
Unlock your door with a knock.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
In this project we will learn how to make password based door lock security system using arduino keypad.
You can simply copy paste the code using arduino ide.
For connecting the keypad with the arduino we are using both analog and digital pins.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
The code for password based door lock security system using arduino keypad is given below.
First of all we will make the connection to the 4 4 keypad.
The arduino board is connected to an lcd and a servo motor.
Digital door lock using arduino circuit diagram.
If you are using arduino mega then there is no need to use analog.
The simply compile it then finally upload it to the atmega328 microcontroller.
Open your door with a special knock using arduino android phone and 1sheeld.
The servo motor is used to push lock or pull unlock.
In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.
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.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
On scanning the wrong tag or on entering the wrong password the system will deny access.
Rfid and keypad door lock and alert system using arduino.
It will open your door only when the right password is entered.
The complete circuit diagram for our arduino based digital keypad door lock project is shown below.
As thefts are increasing day by day security is becoming a major concern nowadays.
Rfid and keypad based door lock using arduino.
Circuit diagram for arduino keypad door lock.
The entire project is controlled by using the arduino.
A 4 4 or 4 3 keypad can be used to enter the desired password.
