Keypad Door Lock System Using Arduino

When you enter the correct 4 digit password the door is opened for 5 seconds.

Keypad door lock system using arduino.

We used analog pins since we need more that 14 digitals pins for this project. In this project we will learn how to make password based door lock security system using arduino keypad. The code for password based door lock security system using arduino keypad is given below. For connecting the keypad with the arduino we are using both analog and digital pins.

Rfid and keypad based door lock using arduino. Digital door lock using arduino circuit diagram. If you are using arduino mega then there is no need to use analog. The complete arduino door lock code can be found at the bottom of this page.

Also it is important to make sure you have added the following keypad library to your arduino ide to. It will open your door only when the right password is entered. A 16x2 lcd will be used for display. So a digital code lock can secure your home or locker easily.

First of all we will make the connection to the 4 4 keypad. Password door lock security system using arduino and keypad in this tutorial you will learn how to make the most efficient password protected door lock security system using arduino and a keypad. The components required for this project are as follows. In this project we are going to make a keyless door lock system which uses a 4x4 keypad to enter the keys and a dc lock to open or close the door.

Rfid and keypad door lock and alert system using arduino. The simply compile it then finally upload it to the atmega328 microcontroller. You can directly upload the code but it is recommended to read the below paragraphs to understand how the code works. As thefts are increasing day by day security is becoming a major concern nowadays.

Arduino keyless door lock system with keypad and lcd 0. This is a simple arduino project. 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.

Arduino code for digital keypad door lock. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. Unlock your door with a knock.
