RFID based Door Access or Security Control System
RFID based Door Access or Security
Control System
A
radio-frequency identification (RFID) based access-control or Security control system allows only authorised people to enter a particular zone of an office or
building. Authorised people are provided with unique tags, using which they can
access that particular area. This project is based on RFID, STM32f103C8 ARM
Cortex-M3 development board, a 16x02 LCD module for displaying the status and a
relay or servo motor for opening the door. Fig.1 depicts the block diagram RFID based Door Access or Security Control System.
Block Diagram
Working
Now let’s see how our
RFID reader and ARM Cortex-M3 controller will make Door Access control system.
The basic working principle is very simple. When we place relevant RFID card
near the MIFARE 13.52 MHz, the controller will read the data via SPI (Serial Peripheral
Interface). If any card that match with the existing stored card in the code
access will provided otherwise access denied. LCD 16x02 will display the all
the messages like Swipe your card, Access Granted etc. Every time when user
show his card the buzzer sounds.
Software and IDE’s used in the Project
C- Language, Keil
MDK ARM V5, Atollic TrueStudio for STM32

Getting Started With STM32 BluePill Part - Installation
In this Tutorial we are going to prepare our Arduino IDE to program
STM32F103 using Arduino IDE.
Step 1: If you have not installed the Arduino IDE in your Laptop/PC
please download and install the Arduino IDE by clicking the
following link.
Please Click
Here to Download Install Arduino IDE.
Note: Make sure to download your
Corresponding OS software.
Step2: Extract Download ZIP file into your local C drive i.e. C:\
Step3: Open the folder and double click on Arduino.exe and you would see
window as shown.
Step4: After the Arduino IDE open and download the required packages for
the STM32 board. This can be done by selecting
File -> Preferences.
Step5: Clicking on Preferences will open the below shown dialog box. In
the additional Boards Manager URL text box paste the below link.
and press OK.
Step6: Now go to Tool -> Boards -> Board Manager. This
will open the Boards manager dialog box, search for “STM32F1” and install the
package that appears.
Step7: After Installation “STM32F1” package the Board Manager should
like as shown.
Step8: After the package, installation is completed. Go to Tools and
scroll down to find the Generic STM32F103C series as shown below. Then make
sure the variant is 64kFlah type, CPU speed is 72MHz and change the upload
method to ST-Link.
Finally, we have completed the installation process. So we will
see how to Blink on Board LED which is basically Hello World! programme.
Getting Started With STM32 BluePill Part - Introduction
