Making a LilyPad Musical Patch

Sew a patch that plays a tune. A LilyPad buzzer and a button let the microcontroller sing a short melody whenever you press it — a musical badge, a fabric greeting card, or a costume piece. This project introduces the buzzer and the Arduino tone() function that turns pin signals into notes.

Sew the board, buzzer and button

Sew a LilyPad Arduino, a LilyPad buzzer and a LilyPad button onto felt. Wire it: the buzzer's + tab to pin 9 and its - tab to -; the button's tabs to analog pin A2 and to -. Keep the lines from crossing.

Upload the melody sketch

Paste this sketch and upload. Pressing the button plays a short rising scale on the buzzer.

lilypad_musical_patch.inoarduino
// Press the button to play a short tune on the LilyPad buzzer.
// Buzzer + on pin 9, button between pin A2 and - (GND).

const int BUZZER_PIN = 9;
const int BUTTON_PIN = A2;   // read as a digital input, pressed = LOW

// A short tune: note frequencies (Hz) and how long each plays (ms)
int melody[]    = { 262, 294, 330, 349, 392 };  // C D E F G
int durations[] = { 200, 200, 200, 200, 400 };

void setup() {
  pinMode(BUZZER_PIN, OUTPUT);
  pinMode(BUTTON_PIN, INPUT_PULLUP);  // built-in pull-up: unpressed reads HIGH
}

void loop() {
  if (digitalRead(BUTTON_PIN) == LOW) {   // button pressed
    for (int i = 0; i < 5; i++) {
      tone(BUZZER_PIN, melody[i], durations[i]);
      delay(durations[i] + 50);
    }
    noTone(BUZZER_PIN);
  }
}

Press to play, then compose

Press the button — you should hear the five notes. Change the tune by editing the melody[] frequencies (higher number = higher note) and the durations[] in milliseconds, then re-upload. Add more notes to both arrays to make a longer song.

Go wireless and wear it

Unplug the FTDI, sew a LilyPad coin-cell holder to the board (+ to +, - to -), drop in a CR2032 and switch on. Sew the felt onto a badge or card — press it to play your tune anywhere.
