Week 4 - Testing component (RFID, LCD)

Image
              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...

Week 3 - Finding the right library for the components.

Image
               This week, I've received the ordered components.  The Arduino environment can be extended through the use of libraries, just like most programming platforms. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data.                      The Arduino IDE comes with a set of standard libraries for commonly used functionality. These libraries support all the examples included with the IDE. Standard library functionality includes basic communication functions and support for some of the most common types of hardware like servo motors and character LCD displays.  Standard Libraries are pre-installed in the "Libraries" folder of the Arduino install.                    The library of components downloaded are for the GSM, RFID and LCD. The library for the GSM is s...

Week 2 - Buying part for the project.

Image
      For this week, I've decided to buy the parts needed for this project. I ordered the parts online as it is easier and the price is cheaper compared to in-store purchasing. Shopee is the online platform chosen to buy the parts as it offers a secure purchasing process. The parts that are purchased also include the relay module and 3 Li-ion lithium batteries. The total cost is RM 149.59 which is slightly higher than predicted in the FYP report. The increase in price is due to the improvement made to the project. Estimated Cost: Actual Cost:

Week 1 - Improvement of the project.

     For the first week of Final Year Project 2 (FYP 2) progression, I reviewed the comments given by the assessors on my project during the project presentation of Final Year Project 1. The comments are supposed to help improve the project.      The improvement to be made is the addition of a relay into the circuit.  Relays are the switches that aim at closing and opening the circuits electronically as well as electromechanically. It controls the opening and closing of the circuit contacts of an electronic circuit. The relay is used to control the opening and closing of the solenoid door lock. Also, 3 double A batteries with a total of 12v are used to supply power to the solenoid door lock.     The second improvement to be made is for the GSM to be having two-way communication with the user. Currently, the GSM only function to send alert notification to the user if an unauthorized person is trying to enter the door. So for the improvement, t...
