Using Arduino Programming Questions
#1

Hi, i want to read some RFID card IDs, and save them. But i got some problem:( Can I get some advices??
Here’s my source cord, and serial monitor.

#include <MFRC522.h>
#include<SPI.h>
#define RST_PIN 9
#define SS_PIN 10

MFRC522 mfrc(SS_PIN, RST_PIN);
char test[3];

void setup(){
Serial.begin(19200);
SPI.begin();

mfrc.PCD_Init();
}

void loop(){
if ( !mfrc.PICC_IsNewCardPresent() || !mfrc.PICC_ReadCardSerial() ) {

delay(500);
return;
}

Serial.print(“Card UID:”);

for (byte i = 0; i < 4; i++) {
Serial.print(mfrc.uid.uidByte*); *

  • Serial.print(" "); *

  • }*

  • Serial.println();*

  • test[0]=mfrc.uid.uidByte[0];*

  • test[1]=mfrc.uid.uidByte[1];*

  • test[2]=mfrc.uid.uidByte[2];*

  • test[3]=mfrc.uid.uidByte[3];*

  • Serial.print(“test:”);*

  • for(byte j=0;j<4;j++){*

  • Serial.print(test[j]);*

  • Serial.print(" ");*

  • }*

  • }*

But i got some problem

First fix the problem with the way that you posted your code, unless, of course, it really is partially in italics

Did you read this before posting a programming question
