1. Demo

2. Code

// the setup routine runs once when you press reset:
void setup() {
  // initialize the serial
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
int i = 0;
void loop() {
Serial.write("*** Test(");
  Serial.print(i);
  Serial.write(") ***\n");
  delay(100);
i++;
}
