When using multiple rfid tags in your example, you must have a break statement in the code. if (strID == RFID_Correct[i]) { scanStateFlag = 1; found = 1; } Should be: if (strID == RFID_Correct[i]) { scanStateFlag = 1; found = 1; break;//(Important to have if we use more than 1 rfid tag) } Defining more than 1 rfid tag: //Using 2 rfid tags #define RFID_AccessCards 2 String RFID_Correct[RFID_AccessCards] = {"2c:d7:c3:a5", "2c:d7:c3:b8"}; //Using 4 rfid tags #define RFID_AccessCards 4 String RFID_Correct[RFID_AccessCards] = {"2c:d7:c3:a5", "2c:d7:c3:b8""1c:d7:c3:a5", "1c:d7:c3:b8"};
Great tutorial thanks, Its very helpful Just a quick bug-fix I think that the"int found = 0;" needs to be before the "for" loop when using an array with more than one element. In your example code 'found' gets reset on each cycle of the for loop, consequently only the last string in the array is considered.
You can add a break statment to if you use more than 1 rfid tag. Like this: if (strID == RFID_Correct[i]) { scanStateFlag = 1; found = 1; break;//(Important to have if we use more than 1 rfid tag) }
There is a typo on your blog.The link to RFIDScanner.ino. It says...Arduino LCD Menu. Blog site: eeenthusiast.com/arduino-rfid-tutorial-implementation-rc522-module-read-example-project/ Typo: The full program we will be implementing in this project is available here: Arduino LCD Menu. The Arduino IDE used is version 1.6.9.
Hola amigo, pero tengo un problema al compilar la biblioteca de Miguel Balboa, y me sale este error no sé cómo resolverlo, el agradecimiento a alguien que me ayude MFRC522 clase no tiene un elemento llamado 'PICC_Halta'
