Keypad Door Lock Arduino

Digital door lock using arduino circuit diagram.

Keypad door lock arduino.

Arduino keyless door lock system with keypad and lcd 0. First of all we start from the brain of this project which is the arduino uno board. The components required for this project are as follows. This is a simple arduino project.

The code for password based door lock security system using arduino keypad is given below. Simple code for arduino keypad door lock systems for beginners. Circuit diagram for arduino keypad door lock. Then connect the last two pins on the 4x4 keypad module to digital pins 3 and 2 on the arduino.

After working on the code and fixing many bugs due to simple mistakes the keypad lock works with a three digit code which is 427. Hello you all i ve been working on a lock system for a while i started looking for some codes to use in my project but unfortunately i found a lot of complex ones and most of them have some fails especially when they use pointers you can try the. Connect the first six pins on the 4x4 keypad with the a0 and a5 pins on the arduino. Green open and red closed.

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. A 16x2 lcd will be used for display. First connect the 4x4 keypad to the arduino. The complete circuit diagram for our arduino based digital keypad door lock project is shown below.

The connections for connecting the lcd with the arduino are as follows. You can simply copy paste the code using arduino ide. 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. After that connect the lcd to the arduino.

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. When you enter the correct 4 digit password the door is opened for 5 seconds. For connecting the keypad with the arduino we are using both analog and digital pins. Learn how to use keypad with arduino how to connect keypad to arduino how to code for keypad how to check keypad password how to program arduino step by step.

When you turn on the keypad the red light will be on. There are red and green led light to show if the keypad is locked or unlock. The keypad lock has become a success. First of all we will make the connection to the 4 4 keypad.

The servo motor is used to push lock or pull unlock. If you are using arduino mega then there is no need to use analog. We used analog pins since we need more that 14 digitals pins for this project.
