Inspiration

Wanted to promote a safer environment for students at UF whilst being relatively cheap.

What it does

A security system that relies on scanning badges to grant access/entry.

How we built it

Wanted to incorporate an RFID into the system so that individuals could use a lightweight key/card as a pass.

Challenges we ran into

Wanted to rely on using ESP32s to wireless communicate between the RFID and our OLED. Unfortunately, we could not get them to work properly.

Accomplishments that we're proud of

Successfully made a prototype of the security system. Checks RFIDs through an access-granted database.

What we learned

We learned how to breadboard, display visuals on an OLED, and interface with an RFID chip. Although the final prototype does not use the ESP32, we did spend an extensive amount of time learning how to use it. We were able to communicate with the RFID and OLEDs separately, but not simultaneously.

What's next for Circuit Secure

Figuring out how to incorporate the ESP32s into our current project so that data about RFIDs that request access to the system can be sent wirelessly to the system.
