Arduino RFID Card Scanner
This long-running project started three months ago when I had the idea of developing a device that can emulate building access cards. Unfortunately, I have realized this is not feasible, and have settled for a device that can simply read the UID (unique ID) of most types of RFID cards/tags.
Nonetheless, this project has lead to me learning a variety of new skills, as well as making use of previous ones:
Electrical soldering.
Coding in C++
Arranging electrical circuits.
Designing and tolerancing parts in SolidWorks.
Initial circuit setup using a large breadboard and an inferior RFID module.
Final setup using a small breadboard and a superior RFID module.
Empty 3D-printed housing.
Soldering through-hole pins to the RFID module.
C++ code running on the Arduino microcontroller.
Circuit diagram for connecting the LCD display.
