Arduino Door Lock with Password || Proteus simulation

Arduino Door Lock with Password is the simplest project for every new Arduino learner who wants to start learning the basic LCD and Keypad Interfacing with Arduino.
In this Simple Arduino Project for beginners, we Created an Arduino door lock with password protection. In this project, we also see Arduino keypad password example and Arduino interfacing with 16x2 character LCD. This password-based door lock system using Arduino is very useful as a learning activity for beginners. We used the Arduino keypad library for interfacing a 4x3 keypad with Arduino.
The core features of this project are as follows
This is an embedded C Arduino project for beginners as well as intermediate programmers
User enter 6 digits password via 4x3 keypad
With every keypress, there is an indication on 16x2 LCD
After 6 keys press the code will match entered keys with a predefined password array
If the password is matched Lock will be opened for 2 seconds and will close again.
If a user enters the wrong password, Red LED will be on (which could also be a buzzer) and the User will be prompted about the wrong password on 16x2 Character Lcd.
