Using a Piezo Element and Arduino, you can play jingle bells using this code sample.

	int speakerPin = 5;
	int length = 26;
	char notes[] = "eeeeeeegcde fffffeeeeddedg";
	int beats[] = { 1, 1, 2, 1, 1, 2, 1, 1, 1, 1, 4, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2};

	int tempo = 300;
	void playTone(int tone, int duration) {
	for (long i = 0; i < duration * 1000L; i += tone * 2) {
	digitalWrite(speakerPin, HIGH);
	delayMicroseconds(tone);
