Week 4 - Testing component (RFID, LCD)
For this week, I tested the component to be used for the RFID door lock with alert system. The component tested is the RFID reader and LCD module. The RC522 RFID module based on MFRC522 IC from NXP is one of the most inexpensive RFID options that users can get online for less than four dollars. It usually comes with a RFID card tag and key fob tag having 1KB memory. For the RFID reader, it is connected to the Arduino Uno. The pin connections are shown below. For the codings, it is taken from the library named RC522. The coding is run using Arduino IDE. The coding is then compiled and uploaded to the Arduino Uno. To test the RFID, open the serial monitor in the Arduino IDE. Then place the RFID card on the RFID reader. The card id will then b...
