Security is a vital concern around the world and it has been major thread for all confidential departments. This work is based on Arduino and is used for the security purpose. .Arduino is an open-source prototyping platform based on easy-to-use hardware and software. Arduino uses an ATmega328 microcontroller. As security is very essential now a day, so by using this project only the authorized person will be allowed to enter by entering the correct password. The circuit is tested in proteous and is working. It is very simple, cost effecting and secure. The lock can be open if the password entered is correct and match to the password which is already stored in the internal memory. It also consist a LCD display which is used to interface with the project to output lock status. This project can be used in ATMs, doors of houses, lockers, offices and anywhere where security is needed.
