1. Since the RFID module works with SPI communication we have connected the MISO,MOSI,SCK and NSS pin to the SPI pins of the Arduino Uno board.

Now it’s time to take a look at the code of the project.In order the project code to compile we need to include some libraries.

As you can see the connections are pretty simple. Next, we connect both GNDs to the breadboard GND rail. 15 0 obj

The upper part of the screen can only display yellow, the lower part only blue.This OLED display is very bright, and it has a great library support. Since the display can also work at 3.3V we connect the Vcc from both modules to the breadboards positive rail.

Kali ini saya akan berbagi Tutorial Pembacaan RFID Card dan Tag Input RFID-RC522 Menggunakan Arduino Uno R3. This chip does not have a battery in order to get power.

<> I have built a simple project which reads the Unique ID (UID) of each RFID tag we place close to the reader and displays it on this OLED display.
The power consumption of this display is around 10-20 mA and it depends on how many pixels are lit.The display has a resolution of 128×64 pixels and it is tiny in size. The same chip exists in keychain RFID tags as well.Each RFID tag has a unique number that identifies it.

At first, let’s connect the power of both the reader and the display. endobj <> That’s it. Su internet non si trovano tante guide su come utilizzarla con Arduino e quindi ho deciso di condividere con voi il codice che ho creato per far si che, ... (rispettivamente sull’altro lato dei collegamenti di Arduino uno). endobj

stream The RFID module is powered by the 5V pin of the Arduino. If the values are the same, we display the UNLOCK message, else we don’t display this message.Of course, you can modify this code in order to store more than 1 UID values in order the project to recognize more RFID tags.

If the UID of the tag is equal to a predefined value that is stored in Arduino’s memory, then in the display we are going to see the “Unlocked” message. <> You only need to connect two wires except for Vcc and GND.

I will use an Arduino UNO and RFID RC522 (MIFARE protocol).Upon scanning the right tag and entering right pass, it will open door and send confirmation message otherwise it will send alert message.Here we are with the classic RFID door lock. So we are going to use the hardware SPI pins of the Arduino UNO. This is Nick from educ8s.tv and today we are going to learn how to use this RFID Reader wit...Dear friends welcome to another tutorial. If I place a flashlight under this RFID card you can see the small chip and the coil that surrounds it. We now have to connect the OLED display with Arduino using the I2C interface. 12 0 obj

It is the easiest way to add a display to your Arduino project. Now we are ready to take a quick look at the code.At first, we declare the value of the RFID tag that we want the Arduino to recognize.

endobj Dear friends welcome to another tutorial. We can easily build a security system with a reader like this one or build more fun projects.My main intention is to build some interactive games for kids using this RFID reader and a lot of RFID tags. 16 0 obj The complete circuit diagram to interface RFID RC522 with Arduino is given below. Now that we know everything about the module, we can begin hooking it up to our Arduino! The pin RST can be connected to any digital pin on the Arduino. 14 0 obj The cost of the RFID reader and these two RFID cards is around $4.This is a very nice display to use with Arduino. endstream endobj rfid.PCD_Init();display.begin(SSD1306_SWITCHCAPVCC, 0x3C);

<> There are two variations of the display. stream Dear friends welcome to another tutorial.

Do you plan to use it in any of your projects? endobj MISO pin goes to digital pin 12. Next, we initialize the RFID reader and the display.After this, in the loop function, we check for a tag on the reader every 100 ms. 11 0 obj
