Examples   
String str1 = "CCCP"; 
String str2 = "CCCP"; 
// Tests to see if str1 is equal to str2 
if(str1.equals(str2) == true) { 
  Serial.println("Equal");  // They are equal so this line will print 
} else { 
  Serial.println("Not equal"); 
} 


String str1 = "CCCP";   
char str3[] = "CCCP"; 
// Tests to see if str1 is equal to str3   
 
void setup() { 
  Serial.begin(9600); 
  if(str1.equals(str3) == true) {   
    Serial.println("Equal");  // They are equal so this line will print   
  }  
  else {   
    Serial.println("Not equal");   
  }  
   
  if(str1.equals("CCCP") == true) {  // Testing directly 
    Serial.println("Equal");  // They are equal so this line will print   
  }  
  else {   
    Serial.println("Not equal");   
  }  
} 
 
void loop() { 
  // Nothing for loop()
