Circuit Documentation
Summary
This document provides a detailed overview of a circuit that integrates an Arduino UNO microcontroller with an RFID-RC522 module. The Arduino UNO serves as the central controller, while the RFID-RC522 module is used for reading RFID tags. The document includes a list of components, wiring details, and the embedded code used in the microcontroller.

Code Documentation
Arduino UNO Code
File Name: sketch.ino
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
This code is a basic template for the Arduino UNO. The setup() function is where you initialize your settings, and the loop() function is where the main code runs repeatedly. Currently, both functions are empty and need to be filled with the appropriate logic for interacting with the RFID-RC522 module.
This concludes the documentation for the circuit. For further details or modifications, please refer to the specific component datasheets and the Arduino programming guide.
