Note: different Arduino boards have different I2C pins. The following table shows the connection between Arduino UNO & DS3231 Module: It works on I2C Communication Protocols with SDA and SCL pins. So we can have accurate TIME and DATE from the RTC module whenever we want.ĭS3231 is a six terminal device, out of the two pins are not compulsory to use. RTC modules are simply TIME and DATE remembering systems that have battery setup which in the absence of external power keeps the module running. The following table shows the connection between Arduino UNO & SD Card Module: This module will greatly expand the capability an Arduino can do with their poor limited memory. SD module has various applications such as data logger, audio, video, graphics. This module has an SPI interface which is compatible with any sd card and it uses 5V or 3.3V power supply which is compatible with Arduino UNO/Mega. It allows you to add mass storage and data logging to your project.

The pin out is directly compatible with Arduino, but can also be used with other microcontrollers. The micro- SD Card Module is a simple solution for transferring data to and from a standard SD card. If you’re using another Arduino board, check the Arduino documentation. Note: different Arduino boards have different SPI pins. The following table shows the connection between Arduino UNO & RFID MFRC522: The open-hardware community already has a lot of projects exploiting the RC522 – RFID Communication, using Arduino. The module uses SPI to communicate with microcontrollers.

The S50 RFID Cards will ease up the process helping you to learn and add the 13.56 MHz RF transition to your project. RC522 – RFID Reader features an outstanding modulation and demodulation algorithm to serve effortless RF communication at 13.56 MHz. The MF RC522 is a highly integrated transmission module for contactless communication at 13.56 MHz. RC522 – RFID Reader / Writer 13.56MHz with Cards Kit includes a 13.56MHz RF reader cum writer module that uses an RC522 IC and two S50 RFID cards. IoT Based RFID Attendance System Using Arduino ESP8266 & Adafruit.io You can also check the advance version of the same project: Fingerprint Sensor Based Biometric Attendance System using Arduino RFID EM-18 Based Attendance System using Arduino & LCD DisplayĢ. Similarly, RTC Module DS3231 or DS1307 is used to store time information.īut before beginning you can see our earlier projects that are based on Attendance System:ġ. We are also interfacing SD Card Module as a Datalogger where the data is saved in text format. For this, we are interfacing the MFRC522 RFID SPI module with Arduino. It also shows if you are late or in time accordingly to a preset hour and minute. When you swipe an RFID tag next to the RFID reader, it saves the user UID and time in an SD card. In this project, we will make RFID MFRC522 based Time Attendance System Using Arduino Board.

In short, its a new emerging technology which is quite useful. We have seen it in many movies that when someone places one’s card over some machine then the door opens or closes. Nowadays it is extensively used in offices where employees have issued an RFID card and their attendance is marked when they touch their card to the RFID reader. It’s a new technology and is expanding day by day. It is an RFID module and is used for scanning RFID cards. MFRC522 RFID Reader is a very simple yet effective module. In this project, we have designed RFID RC522 Based Attendance System Using Arduino with Data Logger.
