# RFID on Arduino: A Comprehensive Guide ## Understanding RFID Technology with Arduino RFID on Arduino opens up a world of possibilities for makers, hobbyists, and professionals alike. As someone who has worked extensively with RFID systems, I've found that combining RFID technology with Arduino microcontrollers creates incredibly versatile solutions for access control, inventory management, and interactive installations. ## My Personal Journey with RFID on Arduino When I first started experimenting with RFID on Arduino, I discovered I had a natural aptitude for understanding the communication protocols between RFID readers and Arduino boards. This skill allowed me to quickly develop functional prototypes that others struggled with for weeks. One of my most successful projects involved creating a smart library system using RFID on Arduino that tracked books automatically. ## Technical Specifications for RFID on Arduino Components For those implementing RFID on Arduino systems, here are the technical specifications for common components: **MFRC522 RFID Module:** - Operating Frequency: 13.56 MHz - Communication Interface: SPI, I2C, UART - Operating Voltage: 2.5V to 3.3V - Chip Code: NXP MFRC522 - Dimensions: 40mm x 60mm x 10mm - Read Range: Up to 50mm **Arduino-Compatible RFID Reader Specifications:** - Microcontroller Compatibility: Arduino Uno, Mega, Nano - Supported Card Types: Mifare 1K, 4K, Ultralight, DESFire - Data Transfer Rate: Up to 424 kbps - Antenna Dimensions: 45mm x 45mm integrated - Power Consumption: 13-26mA during operation *Note: These technical parameters are reference data.
