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.

Connect the programmer

Plug the LilyPad FTDI onto the programming header and connect the USB cable. Open the Arduino IDE and select the LilyPad Arduino board and its serial port.

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.
