In the for loop that prints the uid, I tried putting this line of code to store the uid in a string. String userid = mfrc522.uid.uidByte[i] < 0x10 ? 0 : if (mfrc522[reader].uid.uidByte, mfrc522[reader].uid.size = 30 75 7E 7A) uid.uidByte is NOT a text string; That is not how you compare two text strings. You would In order to get the HEX string you can use this code : String UID_HEX=; Serial.print(Printing HEX UID : ); for (byte i = 0; i < mfrc522.uid.size; i++) {String

Those who have already UID for the RFID tag that you need to give access can skip this part. After finishing up all the circuit connections properly, connect the Arduino board to the computer, then go to File - Examples - MFRC522 - DumpInfo and upload the code using the Arduino IDE software. To get the UID now place the specific RFID tag that you need to provide access. Now, you would be. Arduino. The Arduino will read the RFID tag from the MFRC522 reader. It will retrieve the RFID detail from either the tag or key. We will extract the UID of each tag or key whenever we placed it near the reader. The extracted UID will then be sent to the ESP 8266 ESP-01 thru the serial interface. The ESP8266 ESP-01 would then communicate with. Now i have added a RFID sensor for scanning materials (RFID tags). With the current script in Unity (and FirmateStandard on arduino) i don't get the RFID working.
