[ARDUINO] RFID讀取

接線方法就跟上面這篇一樣 但是我不知道為什麼reset接腳要把它改成第9接腳(我之前文章設定都是第5 但是卻不能work 我程式碼也有改了)

反正不管怎樣 把接腳改掉後 照下面這樣的程式碼輸入即可

如果你是第一次玩 記得去下載 <SPI.h> <MFRC522.h>這兩個函示庫匯入

這兩個函示庫上網google隨處可以下載的到

/*
* MFRC522 - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT.
* The library file MFRC522.h has a wealth of useful info. Please read it.
* The functions are documented in MFRC522.cpp.
*
* Based on code Dr.Leong ( WWW.B2CQSHOP.COM )
* Created by Miguel Balboa (circuitito.com), Jan, 2012.
* Rewritten by Søren Thing Andersen (access.thing.dk), fall of 2013 (Translation to English, refactored, comments, anti collision, cascade levels.)
* Released into the public domain.
*
* Sample program showing how to read data from a PICC using a MFRC522 reader on the Arduino SPI interface.
*----------------------------------------------------------------------------- empty_skull
* Aggiunti pin per arduino Mega
* add pin configuration for arduino mega
* http://mac86project.altervista.org/
----------------------------------------------------------------------------- Nicola Coppola
* Pin layout should be as follows:
* Signal Pin Pin Pin
* Arduino Uno Arduino Mega MFRC522 board
* ------------------------------------------------------------
* Reset 9 5 RST
* SPI SS 10 53 SDA
* SPI MOSI 11 52 MOSI
* SPI MISO 12 51 MISO
* SPI SCK 13 50 SCK
*
* The reader can be found on eBay for around 5 dollars. Search for "mf-rc522" on ebay.com.

MFRC522 mfrc522(10, 9); // Create MFRC522 instance.

void setup() {
Serial.begin(9600); // Initialize serial communications with the PC
SPI.begin(); // Init SPI bus
mfrc522.PCD_Init(); // Init MFRC522 card
Serial.println("Scan PICC to see UID and type...");
}

void loop() {
// Look for new cards
if ( ! mfrc522.PICC_IsNewCardPresent()) {
return;
}

// Select one of the cards
if ( ! mfrc522.PICC_ReadCardSerial()) {
return;
}
delay(2000);
// Dump debug info about the card. PICC_HaltA() is automatically called.
mfrc522.PICC_DumpToSerial(&amp;(mfrc522.uid));
}

出來你會看到像是這樣的東西
