STD Arduino based door lock system
Mode:
In this system, I used a 4×4 keypad to enter a password consisting of 4 digits, and pressing the hashtag confirms it. If the password is correct, a green LED will light up for 5 seconds, as well as a servo motor will change its position from 0 degrees to 90 degrees. While the user is not interacting with the system, the red LED will keep blinking every 1 second to indicate that the system is locked.
