Build a Smart Door Lock with Arduino Keypad Servo Motor & Mechanical Lock

As everyone is aware, security is a top priority. The number of theft cases is rising sharply also. Since everyone is worried about the safety of their homes and lockers, a door lock system that uses a password can help. Only after entering the right password will the door open. Objective This project’s major goal is to switch out the conventional door lock system, which uses a mechanical lock and key mechanism, with a password-based system. Minimal power usage Easy to understand and apply Economical Component Required Hardware Arduino UNO: The Arduino Uno-board is a 8 bit-microcontroller. It has I/0 pins including both…
