"Custom PCB: RFID RC522, Arduino, LEDs—Smart Design!"

This project is about creating a compact and efficient custom PCB that integrates an RFID RC522 module, Arduino Uno, two LEDs, and resistors. The goal is to streamline the design, eliminating the clutter of wires and scattered components commonly found on prototyping boards.

Why I Made ItI wanted to simplify the messy layout of components typically spread across breadboards and jumper wires, making the setup more portable, robust, and aesthetically pleasing. Compact PCBs are easier to use, look professional, and can be deployed more reliably in real-world applications.

How It WorksThe PCB houses all components, including the RFID RC522 for scanning tags, an Arduino Uno microcontroller for processing, and LEDs for status indicators. Resistors ensure the LEDs operate safely. The design connects everything seamlessly, making assembly and troubleshooting easier.

Next StepsWith a focus on simplicity and functionality, I’ll test and iterate on the design for optimal performance. The final product will be sleek, durable, and suitable for various RFID-based projects like access control, inventory management, or IoT systems.

Images and videos will highlight:

• The initial scattered prototype.
• The sleek, compact PCB design in action.
• RFID scans triggering LEDs as feedback.

This project merges practicality with innovation, creating something both functional and visually appealing.
