A Hidden Safe Project

While researching different science fair project ideas, I came across a problem scenario and then designed a solution for this problem.

Have you ever tried to store and protect valuables inside your home?
Have you ever been concerned that one day, someone might break into your home and steal your valuables?
If your answer is yes to any of these above-noted questions, then this project is for you.

Most people use bank lockers to store their jewelry and other important items, however, there are many valuable things that we like to keep in a safe place at home. The easy solution would be to buy a safe from a local hardware store which is great but it also presents another problem.

When someone breaks into a house, the first thing they look for is a safe or they stifle through the cabinets. For this reason, I decided to build a password-protected hidden safe.

How the design works:

I constructed a wooden box that is designed to fit perfectly inside your wall. The box is locked using an RF-ID latch, powered through a Microcontroller programmed with a sequence code. This design makes it nearly impossible for any intruder to detect and open this safe without knowing the location, sequence code and having physical access to the scan card.

How my project can be beneficial to an average household:

On average there is about 1 break-in per thirty seconds in the U.S adding up to about 1.03 million break-ins every year. Keep in mind that these stats are just from the U.S. My design could be the perfect hiding spot for your small belongings. Many tend to hide their valuables in drawers or somewhere in their closets when leaving their home, why not keep them in an Arduino-controlled safe hidden in your wall.

You may be interested or curious as to understanding how my design works and functions.

The way my project works is that there is a wooden box that is placed inside a wall. This box has hinges connected to the box's top side, which allowed the box to be opened. I placed an RFID lock inside the box, which can only be opened with a specific scan card, but that's not all. Before you can scan your card to open the safe, you have to enter a specific combination on the buttons that are attached to the side of the wall. Once this step is done, the Arduino microcontroller receiving the signal will initiate the opening sequence. A red light will start to blink, followed by a buzzer buzzing, indicating that the Arduino is now sending power to the RFID receiver. Once the red light turns green, you have twenty seconds to scan your card and to open the safe.

Thank you for giving me this opportunity to present my design.
