This project implements an RFID-based access control system using an Arduino board, an MFRC522 RFID reader, an I2C LCD display, an RTC (Real-Time Clock) module, and indicator LEDs with a buzzer. It ...

The RFID Attendance System is an Arduino-based project that allows for tracking the attendance of individuals using RFID cards. This system utilizes an RFID reader to scan RFID card IDs and displays ...

[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the ...

最近想整打卡系統,基本功能如下: 1.分辨卡主身份 2.判斷出入狀態 (類似地鐵閘機,第一次拍卡=入閘,再拍卡=出閘) Serial.print(」 , 「); Serial.print(rfid.serNum[1],BIN); Serial.print(」 , 「); Serial.print(rfid.serNum ...

2.判斷出入狀態 (類似地鐵閘機,第一次拍卡=入閘,再拍卡=出閘) 3.紀錄出入時間 我係用RC522 RFID module,我係網上搵到相關資料,程式碼如下 但呢段程式碼只能用作分辨卡主身份,並唔能夠判斷出入狀態:?

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...
