 No dynamic memory or interrupts are used; timing is managed with short, fixed `delay()` calls for simplicity.

 ===== Conclusions =====
@@ Line 127: / Line 137: @@
 All planned features—RFID reading and comparison, servo-driven latch control, I²C LCD messaging, and LED feedback—were successfully implemented.
-===== Conclusions =====
+===== Download =====
-Reliability: Over 100 total scans (both valid and invalid), the system behaved correctly in every case, with no missed reads or false accepts.
+{{pm:prj2025:vstoica:proiect_petreaoctavian.zip?800|}}
-Performance: The combined detection-to-actuation delay (RFID read + decision + servo movement) averaged under 500 ms, providing a near-instant response to the user.
+===== Bibliography / Resources =====
-Power Profile: In idle state the controller plus peripherals draw approximately 200 mA; when the servo is moving, peaks reach about 900 mA, within the capacity of the chosen 2 A supply.
+Software Resources
+Arduino IDE
+Arduino Integrated Development Environment, version 1.8.x
+https://www.arduino.cc/en/software
-User Feedback: The LCD updated instantly with status messages, and the LEDs provided unambiguous visual confirmation of access granted or denied.
+Arduino Reference
+Official documentation for Arduino core functions, libraries, and API.
+https://www.arduino.cc/reference/en
-These results demonstrate that the ** Door Lock Access Control System ** meets the design goals for accuracy, responsiveness, and stability in a prototyping environment.
+MFRC522 Library
+MIFARE® RC522 RFID reader library for Arduino (miguelbalboa/rfid).
+https://github.com/miguelbalboa/rfid
-All planned features—RFID reading and comparison, servo-driven latch control, I²C LCD messaging, and LED feedback—were successfully implemented.
+LiquidCrystal_I2C Library
-===== Download =====
+I²C interface library for 16×2 LCD modules.

+SPI Library (built-in)
-O arhivă (sau mai multe dacă este cazul) cu fişierele obţinute în urma realizării proiectului: surse, scheme, etc. Un fişier README, un ChangeLog, un script de compilare şi copiere automată pe uC crează întotdeauna o impresie bună ;-).
+Arduino’s built-in SPI master library for communicating with SPI peripherals.
+https://www.arduino.cc/en/Reference/SPI
-Fişierele se încarcă pe wiki folosind facilitatea **Add Images or other files**. Namespace-ul în care se încarcă fişierele este de tipul **:pm:prj20??:c?** sau **:pm:prj20??:c?:nume_student** (dacă este cazul). **Exemplu:** Dumitru Alin, 331CC -> **:pm:prj2009:cc:dumitru_alin**.
