Password Protective Door

MoonCampaign by Arnav (12 years)

Arnav created an innovative project called the Password Protected Door. The system uses Arduino, LEDs, and a servo motor to simulate a secure entryway. When the correct password is entered, a green light turns on and the door opens, while a wrong password keeps the red light glowing and the door locked.

All about Arnav project

Arnav ecently presented his creative project, the Password Protected Door. Built with Arduino technology, this project combines coding and electronics to design a simple yet effective security system. The idea behind it is straightforward: protect a door with a password so only authorized people can enter.

Arnav programmed the system so that when the correct password is typed, the green LED lights up and the servo motor rotates, simulating the opening of a door. If the wrong password is entered, the red LED glows, and the door remains locked. To make it practical, Arnold included an additional feature: a button that allows people inside to open the door without entering a password. This adds both security and convenience, mimicking how real-world systems work. Arnav mentioned that this project could be used not only for homes and safes but also for banks, hotels, and even rental services for cars or bikes. He also discussed the importance of reinforcing the system with stronger materials in real-life scenarios.
