How to convert int to string on Arduino?

Question

How do I convert an int, n, to a string so that when I send it over the serial, it is sent as a string?

This is what I have so far:

int ledPin=13; int testerPin=8; int n=1;  char buf[10];  void setup() {     pinMode(ledPin, OUTPUT);     pinMode(testerPin, OUTPUT);     Serial.begin(115200); }  void loop() {     digitalWrite(ledPin, HIGH);     sprintf(buf, "Hello!%d", n);     Serial.println(buf);     delay(500);     digitalWrite(ledPin, LOW);     delay(500);      n++; }

Use like this:

String myString = String(n);
