Security is an imperative worry all throughout the planet and it has been significant string for every single classified division. This work depends on Arduino and is utilized for the security reason. Arduino is an open-source prototyping stage dependent on simple to-utilize equipment and programming. Arduino utilizes an ATmega328 microcontroller. As security is extremely fundamental now daily, so by utilizing this undertaking just the approved individual will be permitted to enter by entering the right secret key. The circuit is tried in proteous and is working. It is extremely basic, cost affecting and secure. The lock can be open if the secret word entered is right and match to the secret phrase which is as of now put away in the inner memory. It additionally comprise a LCD show which is utilized to interface with the task to yield lock status. This undertaking can be utilized in ATMs, entryways of houses, storage spaces, workplaces and anyplace where security is required.
