Everything else stays the same, except that we invoke the rfid.write("Circuit basics") when we bring the card closer to the RFID writer.
DATA CARD READER AND WRITER RASPBERRY PI CODE
So we execute the code above as many times as we want to write to different cards. This is mainly because we do not want to write the same information on different cards. import RPi.GPIO as GPIOĪ notable difference between rfidReader.py and rfidWriter.py is that we do not have a while loop in the latter. We create a file called rfidWriter.py and paste the code below. We can see how this works in the code below. To write information on the RFID card, we use another method of the RFID object: rfid.write(). This tells us that our RFID card has the ID 1002059512185 while the RFID tag has the ID 588633495959. You should see something like this being printed to the terminal: Run the Python code above by entering the command sudo python3 rfidReader.py in the terminal. We have placed this code in an infinite loop, which means that the Raspberry Pi will continuously read the output from the RFID module.

To read the RFID card date, we call the read() function and store its output in the variables id and text.įinally, we print the ID and text of the card to the terminal with print(id) and print(text), respectively. Then we use rfid = SimpleMFRC522() to create a new object which we will call RFID. import RPi.GPIO as GPIOįirst, we import the necessary modules. Then, create a Python file rfidReader.py and paste the following code. To do this, connect the components as shown in the diagram above. Our first step will be to read the information on the RFID card.
DATA CARD READER AND WRITER RASPBERRY PI INSTALL
Then, install the MFRC522 Python library with the following command: sudo pip3 install mfrc522 Code to Read the RFID Card You also need to install pip3 with this command: sudo apt-get -y install python3-pip To set up a fully compatible SD card for Raspberry Pi, use the recommended SD card formatting tool to format an SD card large than 32GB to FAT32 or convert exFAT to FAT32 on Windows 10, 8, 7, XP, or Vista.ĭownload EaseUS FREE partition manager and follow the guide below to format your SD card.How to Program the RFID Card Reader with Pythonīefore we get started programming, make sure the SPI interface is enabled on your Raspberry Pi. Your SD card should be prepared in FAT files system, let it be either FAT16 or FAT32, not including large capacity SDHC or SDXC cards which with an exFAT file system. Exit the imager and eject the SD card.Īnother recommend Imager is Win32DiskImager, you can choose the one you like.ĭownload source: Format SD Card to FAT16 or FAT32 for Raspberry Pi 1,2,3 Click "Write" and wait for the writing process to complete. In the device box, select the correct SD card. Open Raspberry Pi Imager and choose the required OS from the list presented. Insert your SD card into the computer with a card reader or an adapter. Download and install the latest version of the Raspberry Pi Imager.
