I Added Proximity Unlock To My 20 Year Old Car (iPhone and Arduino)

In this video, I used Arduino with BLE (Bluetooth Low Energy) to unlock my car remotely using either iPhone or a second Arduino.
I learned about Arduino, electricity, 3D printing, BLE, RF, car wiring, soldering, and more from this one single project.
This project was challenging but satisfying. I hope to be able to create more projects like this in the future that I find interesting.
