//program

//black wire to ground int speakerPin = 8;//red wire connect to pin 8

void setup() {

pinMode(speakerPin,OUTPUT); } void loop() { tone(speakerPin, 2601); // m delay(1000); noTone(speakerPin); delay(500);

tone(speakerPin, 8012); // a delay(1000); noTone(speakerPin); delay(500);

tone(speakerPin, 5092); // h delay(1000); noTone(speakerPin); delay(500);

tone(speakerPin, 1202); // e delay(1000); noTone(speakerPin); delay(500);

tone(speakerPin, 6028); // s delay(1000); noTone(speakerPin); delay(500);
