Digital Keypad Security Door Lock using Arduino ||Tinkercad

Often times, we need to secure a room at our home or office (perhaps a secret dexter’s laboratory) so that no one can access the room without our permission and ensure protection against theft or loss of our important accessories and assets. There are so many types of security systems present today but behind the scene, for authentication they all relay on fingerprint, retina scanner, iris scanner, face id, tongue scanner, RFID reader, password, pin, patterns, etc. Off all the solutions the low-cost one is to use a password or pin-based system. So, in this project, I have built an Arduino Keypad Door Lock which can be mounted to any of your existing doors to secure them with a digital password.
» List of components
• Arduino Uno/Pro/Mini or Custom board using Atmega 328p Microcontroller
• 16 x 2 LCD (Liquid Crystal Display)
• 4 x 3 or 4 x 4 matrix keypad for Arduino
• Servo motor
• Additional components for power supply of 1 Amp 5 Volt mobile charger
• jumper wires, nuts bolts, plastic casing, etc.
» Software
For the software part, I program it using arduino IDE v1.01.

thank you so much for the tutorial, great vid. but is there any way to get rid of the time limit once the door is open? and how do i change the default password.

[@srijangupta4826]

In the code, you'll have char Master Password Length (ig it's in the 13 row) there you can change the passowrd

what is the password

[@flmdsfr9395]

Hello. What does if (customKey == '#') mean?
void loop()
{
if (door == true)
{
customKey = customKeypad.getKey();
if (customKey == '#')
{
lcd.clear();
ServoClose();
lcd.print("Door is closed");
delay(3000);
door = false;
}
}

[@richardhisamoto2329]

the 'delay(3000);' is how long it takes for the door to close, and the rest of it just tells the Audino how to get to that point, and to open and/or close the door.
