} else {
  Serial.println("Not equal");
}
String str1 = String("CCCP");   
String str3 = String("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");   
  }  
} 
 
void loop() {
