Abstract
New, improved locking solutions are replacing older lock systems that use a mechanical lock and key mechanism. These methods combine mechanical and electronic components and are extremely intelligent. One of the standout characteristics of these cutting-edge lock systems is their efficiency and simplicity. Such an automatic lock system comprises of an electronic control assembly that authenticates users through GSM and uses an OTP to control the output. A motor, lamp, or any other mechanical or electrical load could be this output load. Here, we used an Arduino microcontroller to create an electronic code lock system. Our main objective is to build a comprehensive security system using embedded (Microcontroller) and wireless (GSM device) technology. The suggested solution offers a low-cost service with assured high security when compared to competing security systems.
