Arduino RFID Access Control: RC522 and I2C LCD Setup Guide
2024年6月9日 · This code sets up an access control system using an Arduino, RC522 RFID module, and an I2C LCD display. The system prompts the user to scan an RFID card, reads the card's UID, and checks if it matches a predefined UID.
Arduino RFID RC522 Tutorial - Microcontroller Tutorials
2018年12月29日 · To enable I2C, we must cut the connection of the trace on the board to pin 1 on the IC. This can be done by drilling a hole on a board as shown by user Renate-USB of the Arduino community. After doing this, the RC522 will enter I2C mode with an address of 0x3C.
ESP32: RFID RC522 i2c - Networking, Protocols, and Devices - Arduino Forum
2023年3月10日 · Almost all of them says the RC522 has three communication channels: i2c, spi and uart. But when they come down to the examples, I always see the spi used. In my custom board I would like to use the i2c, but I'm unable to find …
RFID RC522 Interfacing with ESP32 | ESP32 - ElectronicWings
RC522 RFID Modules work on 13.56MHz which is based on the MFRC522 controller which is designed by NXP Semiconductor. The RC522 module supports SPI and I2C communication protocols. Here we are using the SPI communication Interface with the ESP32 board.
RFID Tag/card Verification System : Arduino UNO + RFID RC522
