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.

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.

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.

There are so many types of security systems present today but behind the scene, for authentication they all relay on fingerprint, retina scanner, iris scanner, face id, tongue scanner, RFID reader, password, pin, patterns, etc. Off all the solutions the low-cost one is to use a password or pin-based system. So, in this project, I have built an Arduino Keypad Door Lock which can be mounted to any of your existing doors to secure them with a digital password. Previously, we have also built other interesting door locks which are listed below. Before building our password door locking project, first, we need to collect the required components and then go ahead and follow the step by step building process. First of all, we start from the brain of this project which is the Arduino UNO board.

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.

 - Все хотят поиграть в эту игру. Сьюзан пропустила эти слова мимо ушей. - Да. Шестнадцать. - Уберите пробелы, - твердо сказал Дэвид.

Сьюзан упрашивала его сказать, о чем в них говорилось, но он, кокетничая, отказывался. Тогда она взяла послание домой и всю ночь просидела под одеялом с карманным фонариком, пытаясь раскрыть секрет. Наконец она поняла, что каждая цифра обозначала букву с соответствующим порядковым номером. Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи.
