In this tutorial, we learn how to make door lock system with password using keypad and solenoid lock. Designed and implemented a secure Keypad Door Lock System using Arduino Uno, enabling password-based access control with real-time authentication and automated locking mechanism. 14 hours ago · The keypad is read by an Arduino Nano, which is also responsible for talking to a stepper motor driver to actuate the lock cylinder. 0 Version. IIMSTC Mini Project_01 – "Password-Based Door Lock System" using Arduino, Keypad, LCD, and Servo Motor. Jul 8, 2025 · This project is a DIY Smart Door Lock System using an Arduino Uno, a 4x4 Keypad, IR Sensor, Servo Motor, Bluetooth Module (HC-05), LED, and a Push Button. The servo motor rotates to open the lock when the correct Sep 9, 2025 · The proposed IoT-based smart voice and keypad door lock system using Arduino overcomes the limitations of traditional door lock systems by providing a convenient, secure, and flexible way to unlock doors, meeting the diverse needs of users. It will receive input from both a fingerprint sensor and a keypad, display relevant messages on a screen, and activate amotor to lock or unlock the safe based on the authentication outcome - with TME Education. Since the OTP is valid for only one use and for a short duration, the chances of unauthorized entry are significantly reduced. When the door is unlocked by a correct password, It keeps the door unlocked for 20 seconds, and then automatically lock the door again. The system works on the basis of two-factor authentication. 3K views 00:29 Wireless distance measurement @tme_education Feb 26, 2026 · 7. 1. 9K views 01:00 This DIY Worm Designed and implemented a secure Keypad Door Lock System using Arduino Uno, enabling password-based access control with real-time authentication and automated locking mechanism.

A microcontroller controls the verification process and activates a relay to operate the electronic door lock. Mar 17, 2020 · In this project we have built an Arduino Keypad Door Lock which can be mounted to any of your existing doors to secure them with a digital password. The goal is to create a secure and flexible locking system that can be controlled from both inside and outside the room. The user must enter the received OTP using a keypad or mobile interface to unlock the door. With rising concerns about security, this digital password-based lock can be an effective way to safeguard homes or lockers. In this project, we will make a Password-Based Door Lock Security Systemusing Arduino, a keypad, a servo motor, an LCD, and a buzzer. Mar 20, 2022 · In this Project lets learn how to build a Password based door lock system by interfacing Arduino with 4×4 Keypad to enter the passcode. We also connect an LCD display to make ease of entering passwords and changing the passwords without hardcoding Arduino Again. bzt lcl dci qzo vlz yde pol vpw ued yyh chh ikz ifl cay fll
