Security of personal belongings is a universal problem but the solution has often been boring and mundane. We want to introduce a secure lockbox that has both high-tech security systems along with fun and annoying deterrence systems.

What it does

The Ultimate Lockbox utilizes state-of-the-art technology to keep your personal belongings safe. If the incorrect password is inputted, the user will have to deal with several unfortunate ramifications, including bright red LEDs, a loud (and rather annoying) buzzer, and getting shot with a nerf gun.

How we built it

This project involved interfacing several external components, including LED strips, buzzers, hall effect sensors, servos, and a nerf gun. As such, this project was relatively software intensive. Some of our code built upon concepts developed in class with slight modifications to suit our purposes, but we had to write much of the code ourselves. We ultimately decided not to use any external libraries and embraced the challenge that came with creating a project from scratch.

Challenges we ran into

Some challenges we ran into included using RFID and controlling the nerf gun with the Arduino. While we were not able to get the RFID working in time, we are quite proud of how we interfaced the nerf gun. We eventually decided on making use of the relay in our kit. We initially thought of making use of a MOSFET, but this proved to be difficult since the nerf gun was powered by an external battery pack, meaning that the systems referenced different grounds.

What we learned

We learned how to take a concept, plan it out, and develop it. We also got far more experience in interfacing mechanical components with software. Overall, we enjoyed this project as it provided us with a great learning experience.

What's next for Ultimate Lockbox

The Ultimate Lockbox has lots of room for improvement. We would like to work more on the physical container, as well as introducing even more deterrents into the project!
