У меня "ошибка" с моим кодом

Следующий код выдает мне ошибку:

// RFIDunio.h is from http://learn.robotgeek.com/getting-started-guides/39-robot-kits/151-rfiduino.html
#include <RFIDuino.h> 

byte    keyTag[5] = {0,0,0,0,0};
boolean noise = false;
byte    masterTag[5] = {37,0,0,127,24};
byte    tagData[5];
byte    tagDatas[5];
boolean verifyKey = false;
boolean mastaKey = false;

void setup()
{
  Serial.begin(9600);
  Serial.println("Welcome to my system!");
}

RFIDuino myRFIDuino(1.2);

void loop()
{
  if(myRFIDunio.scanForTag(tagData == true)
  {
    verifyKey = myRFIDunio.compareTagData(tagData, keyTag);
    mastaKey = myRFIDunio.compareTagData(tagData, masterTag);
    if(verifyKey == true)
    {
      digitalWrite(myRFIDunio.led2,HIGH);
      if(noise == true)
      {
        myRFIDunio.successSound();
      }
      Serial.println("Correct Key!" + " UID = " + tagData[5]);
      delay(250);
      digitalWrite(myRFIDunio.led2,LOW);
    }
    else if(mastaKey == true)
    {
      Serial.println("Programming mode activated!");
      delay(500);
      Serial.println("Please scan a card.");
      myRFIDunio.scanForTag(tagDatas == true)
      delay(1000);
      tagDatas[5] = tagData[5];
      Serial.println("Card has been programmed!");
    }
    else
    {

      if(noise == true)
         {
