The Password-Based Door Lock System is a security-focused project that uses an Arduino microcontroller, a keypad, an LCD, and a servo motor to create a cost-effective and efficient door lock mechanism ...

This was followed by fitting the LCD display below the lock mechanism. Arduino and the breadboard were placed behind the setup, and the components were interconnected using jumpers as per the circuit ...

Arduino RFID Door Lock; Arduino Solenoid Door Lock; Raspberry Pi Digital Code Lock; 555 Timer electronic Door lock; RFID Door lock system using Arduino; Before building our password door locking ...

After some time, the door would close. Again if another person arrives and fails to enter the correct password, the door would remain closed, denying access to the person. Circuit Diagram of Password ...

If the entered password is correct then the system opens the door by rotating door motor and displays the status of door on LCD. If the password is wrong then door is remain closed and displays “pwd ...

When the power is disconnected the slug moves outside and locks the door. It doesn’t use any power in a locked state. To drive the solenoid lock you would need a power source that can give 12V @ 500mA ...

Abstract: Today, installing a home security system is a critical study in implementing cutting-edge technology to attain this purpose. One of the most useful technologies to allow remote monitoring of ...

In the next section, we will see the circuit diagram for the Arduino-based RFID Door Lock System. RFID Door Lock System using Arduino Circuit Diagram. The below RFID Door Lock System circuit diagram ...
