In this article, I will explain about the locking and unlocking door by keypad using Arduino. Do not worry, it's easy to implement. If we have this setup then it can be used for home security. It can be used to open and close the door by password through the keypad. It consists of buttons for operating a portable electronic device, telephone, or other equipment. The keypad consists of numeric numbers for the door password.

So there is a lot of robbery, theft going on in and around the world. So, people fear to keep any of their valuables in their homes. Henceforth, many people prefer to keep it in banks. However, in this insecure world even banks are not too safe enough to satisfy people needs. A common man feels his valuables are secured if there is efficiency in security. Hence this project can give effective security in minimal cost. The user will be prompted to enter a password to unlock the door.

Abstract: Security and safety is major concern in every aspect of human life. The number of crimes in theft are increasing day by day security systems are necessary everywhere like banks, offices, home lockers etc. Because of technological advancement new systems are introduced one of such system is password protected electronic locking system that provide great benefit over a traditional lock system, as well as great security , the implemented locker system comprises of arduino, GSM, keypad, buzzer etc, in order to have access to the locker system one should know the correct password ,if any intruder tries to open the locker system the owner will be notified via buzzer and SMS send to his cell phone. Innovative technologies are developed by people to make the human life easier, the world is using technological advances in many different ways, and one of these ways is security system. Because of innovation in electronic field the electronic security systems is getting more importance. Locks are present in both complex and simple design, locks which are simple in design are easy to use often are easy to breach into but the locks that are complex in design are tough to breach but tedious to use. Traditional lock system can be easily broken by the thieves and owner are not even aware of it, today the locker security has reached to high level where control lies in the hands of owner.

Door Lock By Keypad Using Arduino

The result of an accomplished Kickstarter campaign, the UL3 is a keypad door lock with a built-in fingerprint scanner which gives you an additional layer of security. I have figured out how to open doors before, but I didn't use it for personal gain or feel the need to brag about it. Keyless entry systems have been a target for decades; read old Phrack issues for stories, and even listings of the very small complete sets of combinations. Bluetooth enabled features allow you to keep tabs of who comes and goes and issue Access Codes remotely. Pros: Entirely mechanical, so there are no batteries to worry about. I question whether publicly posting these discoveries on a blog is in line with the hacker ethic.

GSM based Door Locking and Unlocking System

This should be a cool and easy project. We will conect a small thin Keypad that I've bought from eBay for less than 70 cnts to one Arduino microntroller. You could use any Arduino boar that you want. Using the KeyPad library we will be able to read each of the 16 buttons that this keypad has using just 8 pins of the arduino. The library use is simple.

Access Control With Arduino + Keypad 4x4 + Servo (UPDATE)

Энсей Танкадо стал изгоем мирового компьютерного сообщества: никто не верил калеке, обвиняемому в шпионаже, особенно когда он пытался доказать свою правоту, рассказывая о какой-то фантастической дешифровальной машине АНБ. Самое странное заключалось в том, что Танкадо, казалось, понимал, что таковы правила игры. Он не дал волю гневу, а лишь преисполнился решимости.

Плечи его отчаянно болели, а грубый камень не обеспечивал достаточного захвата и впивался в кончики пальцев подобно битому стеклу. Беккер понимал, что через несколько секунд его преследователь побежит назад и с верхних ступеней сразу же увидит вцепившиеся в карниз пальцы. Он зажмурился и начал подтягиваться, понимая, что только чудо спасет его от гибели.
