Keypad Based Door Lock System Using Arduino
So a digital code lock can secure your home or locker easily.
Keypad based door lock system using arduino. If you are using arduino mega then there is no need to use analog. A 4 4 or 4 3 keypad can be used to enter the desired password. As thefts are increasing day by day security is becoming a major concern nowadays. The simply compile it then finally upload it to the atmega328 microcontroller.
On scanning the wrong tag or on entering the wrong password the system will deny access. The password based door lock system allows only authorized persons to access the restricted areas. For connecting the keypad with the arduino we are using both analog and digital pins. Just thought of making a password based door lock system in which you can enter the password via the keypad.
First of all we start from the brain of this project which is the arduino uno board. The arduino board is connected to an lcd and a servo motor. It will open your door only when the right password is entered. The servo motor is used to push lock or pull unlock.
First of all we will make the connection to the 4 4 keypad. Rfid and keypad based door lock using arduino. In this post you are going to learn about how to build an rfid and keypad based door lock using arduino. In this project we will learn how to make password based door lock security system using arduino keypad.
Open your door with a special knock using arduino android phone and 1sheeld. The complete circuit diagram for our arduino based digital keypad door lock project is shown below. Circuit diagram for arduino keypad door lock. The entire project is controlled by using the arduino.
The code for password based door lock security system using arduino keypad is given below. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. To open the door the user will have to first scan the right tag and then he will have to enter the correct password. This is a simple arduino project.
You can simply copy paste the code using arduino ide. We used analog pins since we need more that 14 digitals pins for this project. Digital door lock using arduino circuit diagram.
