We are one of those people who always lose their keys. At Texas Tech University, the damage for losing your keys is $50. So after some point, we have gone tired of it and inspired(somewhat!) to put a permanent end to it (Not really, we still use our keys!). That's why decided to come up with our project.
What it does
This is a basic model of an automated lock system where the key is your FINGERPRINTS. Fortunately, it's pretty tough to lose your fingers so, you will technically never lose your keys. The best part is, you will have 10 different options. Smart, isn't it? So what here happens is, you put your fingerprint on the IR fingerprint sensor, so if the system recognizes your fingerprint, it grants you access and the door opens, with a green light on the liquid display. Or else the display goes red.
How we built it
We have used a wooden box, a servo motor, an infrared fingerprint sensor, a regular spring, 2 breadboards, 4 resistors, 2 LED lights, a somewhat functioning liquid display, and lots of jumper wires, and most importantly Arduino codes.
Challenges we ran into
The first challenge we faced that we didn't know how to make sure the door went to its initial position after resetting the fingerprint values. The second challenge is kind of a silly one, the wiring.
Accomplishments that we're proud of
We are proud of the fact that despite being freshmen, and totally new to coding, we have come together, and having a functioning prototype.
What we learned
We have learnt the basic concept of the Arduino framework and the fact how amazing it is to work with hardware and software.
What's next for ENTER AT YOUR OWN RISK!
We have various plans for this project. We plan to work on the software version, so we can provide a better security system. Here's a brief of what we will be working on. We plan to add features like, sending our "clients" notifications anytime someone wants to grant access to his/her facility, giving him/her the option if he/she wants to grant people access they have already given access to, etc. (The inspiration behind that was the login framework from Facebook, haha)!
