(FYP 2) DEVELOPMENT OF RFID DOOR LOCK WITH ALERT SYSTEM USING GSM

           This week will be the final presentation for Final Year Project students. The student will have to present their project and slides to their respective accessors. The students will have to do the presentation via Microsoft Teams. The accessors for my presentation will be madam Norhayati Yussof and sir Yusof Kadase.                This week will also be the week to submit the Final Year Project blog to the supervisor. The deadline given to submit the blog is during the presentation day which is on the 2nd of Jun 2021. The blog will be submitted by giving the link to the supervisor. The purpose of doing the blog is so that the supervisor can monitor the project progress of each week of their students.

           For this week, I submitted the draft of the technical report and final year project report to Sir Izwan. The purpose of submitting the report is so that the supervisors can help the student check their report format and contents, and to help check the plagiarism percentage before submitting the real report. The percentage should not exceed 30% as told during the final year project briefing. The draft report of this project scored 14% after doing the plagiarism check.          I also did the presentation slides for the final year project presentation. The content of the slides was taken from the final year project report. The slides were arranged following the guideline given by the final year project coordinator. 

          For this week, I did a bit of touch-up to the RFID Door Lock System. The door was spray painted so that it looks nicer. There was also a pad to show the user where to place their RFID card. The pad was placed above the RFID reader which is inside the door. The door is shown in the picture below.           I prepared the project demonstration video for the final year project presentation. The video is to show the accessors how the project will function. The video is needed because of the online presentation. At the start of the video, the components used for the system are shown. The video contains how the project looks like, how the door lock system functions if an authorized and unauthorized card is placed on the RFID reader. The video also shows the alert notification that the GSM sent when an unauthorized card is placed. The video is then uploaded to Microsoft Teams.          

           For this week, I wrote the technical report for the RFID Door Lock System with Alert Notification using GSM. A thesis  is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings. The thesis is divided into 5 sections.               First is the introduction of the thesis. This section should include sufficient background information to set the work in context. The aims of the manuscript should be clearly stated. The introduction should not contain either findings or conclusions. Next are the Materials and Methods. This should be concise but provide sufficient detail to allow the work to be repeated by others. The third is the Results. The results should be presented in a logical sequence in the text, tables, and figures; repetitive presentation of the same data in different forms should be avoided  ...

              For this week, I finished writing the last chapter for the technical report which is the conclusion. The main purpose of writing the conclusion is to s ummarize and reflect on the research, make recommendations for future work on the topic, and show the knowledge contributed to the report. The conclusion is aimed to leave the reader with a clear understanding of the main discovery or argument that your research has advanced.               For the recommendations, I recommended for future researchers to use Wi-Fi in exchange for the GSM because GSM needs a good and stable network connection to establish a connection to the network in order to send the alert notification to the user. The second recommendation is to install a backup battery so that the door lock system can function when there is a blackout happening. The final recommendation is to install a security camera to monitor the door from...

            After finishing the project, it is time to do the technical report. For this week, I have done chapter 4 of the report. Chapter 4 is the Results and Discussion of the technical paper. The output of the project is discussed in this chapter of the report. It contains all of the data to support the hypothesis that was proposed in the introduction section. It serves to weave a coherent story and must communicate the findings to the reader in a logical, transparent manner.               This project managed to achieve the objective which is to provide protection for housing areas from any crime.  By observing the flowchart and block diagram, the outcome can be obtained as well as in the flowchart of the project. All the results of the project are shown step by step from turning on the Arduino Uno, waiting for the GSM to establish a connection, placing an authorized and an unauthorized RFID card o...

                For this week, I designed the door structure for the project. The design of the door prototype is done by hand. The size of the door is smaller compared to normal doors as the door is only a prototype. The measurements of the components are taken and written in a note. The design and measurements are then taken to a local carpenter to cut the planks and woods to assemble the door. 2 door hinges are used so that the door can be opened and closed. A door handle is screwed to the door so that users can grab the handle to open the door. All components are screwed inside the door securely so that they do not move around and get damaged. 

           After the new 5V AC to DC power supply and LCD module arrived, I disconnected the damaged LCD and plugged in the new LCD module. The pins connection is just the same as the previous LCD module. Then I connect the 5V power supply to the power jack of the Arduino Uno board and turn on the supply. The LCD worked and I waited for the GSM to establish a connection to test the project. The project runs smoothly as intended. In conclusion, the 5V power supply is sufficient for the project to run.

           After the 12V AC to DC power supply arrived, I plugged it into the Arduino Uno to use it as the main power supply. Before plugging it in, I reupload the programme code once again using Arduino IDE into the Arduino Uno just to make sure it works fine.              Then, I disconnect the Arduino power cable and plugged in the 12V power supply. After plugging in the power supply, everything works fine until the LCD module starts to turn bright and then it has no display. Realizing that the LCD might be broken, I turned off the power supply and checked the LCD. I switched back to the Arduino 5V USB power supply and the LCD remained to show no display.                    After doing some research, I found out that if the Arduino board is supplied using the power jack, the Vin voltage will be the same as the power jack voltage. So this means that the Vin...

           For this week, I am changing the power supply for the Arduino Uno. Before this, the Arduino Uno is using the power supply from my computer. So for the project to be proper, I want to change to supply to be from the wall socket. Before buying the AC to DC power supply adapter, I went to the Arduino website to find out the recommended power supply to be used for the Arduino Uno.           Based on the information from Arduino's website, the recommended input voltage for the Arduino Uno is 7V to 12V. And the limit is 20V. With that information, I ordered a 12V 2A, AC to DC power supply adapter from Shopee to be to power supply for the project. 

    For this week, I assembled all the components together to form a complete circuit for the project. The circuit connections are the same as when testing the components. Except for the GSM, because pin D9 and D10 is occupied by the RFID, the 5VT pin is placed in the D5 pin and the 5VR is placed in the D6 pin of the Arduino. For the power supply, as the  LCD and GSM require 5V of power supply and the Arduino Uno only has one 5V supply, I placed the voltage supply of the LCD to the Vin pin on the Arduino.      After assembling the circuits, I combined the program codes in Arduino Uno so that if an unauthorized RFID card is placed on the RFID reader, the GSM will send an SMS notification to my phone. After uploading the program code into the Arduino Uno, I tried placing an authorized RFID card on the RFID reader. The LCD displayed "Authorized Access" and the solenoid lock opened. Then I placed an unauthorized RFID card on the RFID reader. The LCD displayed "...

         This week is the testing of the final component which is the GSM Sim 900a. Sim 900a is built with Dual Band GSM/GPRS based SIM900A modem from SIMCOM. It works on frequencies 900/ 1800 MHz. Sim 900a can search these two bands automatically. The frequency bands can also be set by AT Commands. The baud rate is configurable from 1200-115200 through AT command. The GSM/GPRS Modem is having internal TCP/IP stack to enable you to connect with the internet via GPRS. Sim 900a is an ultra compact and reliable wireless module. This is a complete GSM/GPRS module in a SMT type and designed with a very powerful single-chip processor integrating AMR926EJ-S core, allowing user to benefit from small dimensions and cost-effective solutions.               To test the Sim 900a, first, need to insert a sim card into the sim card slot provided. Then, power up the Sim 900a using a 5v power supply. When the Sim 900a is turned o...

               For this week, I combined the solenoid door lock, relay, LCD module, and RFID module into 1 circuit. The solenoid door lock is connected to the relay and an external power supply which is the Li-ion batteries because it requires a power supply of 12V. The relay is then connected to the Arduino Uno. The connection is shown below.                                 Then I combine all the codes into 1 file and uploaded it to Arduino Uno. After that, I place the RFID card on the RFID reader to test the solenoid. If the RFID card used is authorized, the Arduino Uno will turn on the relay thus unlocking the solenoid door lock. If the RFID card used is not authorized, the Arduino Uno will receive the information and lock the solenoid door lock. Below is the Arduino codes.
