Story

This is an Arduino project that plays "We Wish You a Merry Christmas" and brightens the place with LEDs situated to create a snowflake.

While producing this project, I found that the bigger the snowflake piece is the easier it is to connect all the LEDs as there is much more space. You have to be much more precise with a smaller board.

I made the hardware using cardboard gluing it with the hot glue gun.

The circuit diagram is quite a handful. The circuit diagram is picturing that all the outer LEDs are interconnected and are powered by a single digital pin and ground. The inner LEDs are individually wired to the Arduino with each with its pin. And of course, the buzzer also has its pin.

While using the buzzer, you will have to use the tone() function. When using this function do not use the digital pins 11 and 3. You can use millis() instead of delay() if you make the LED lights and the song separate independent events.

It would be helpful for the Arduino Community to provide suggestions to contribute to my project. I will also answer any questions you have in the comments.

Code

int buzzer = 2; // 2 = The pin you use for the buzzer on the Arduino
int x = 450;

void setup() {
  pinMode(buzzer, OUTPUT); // Telling the Ardiuno that Buzzer is an Output
}

// New Function
void We_Wish_You_A_Merry_Christmas() {
  // Tone(pin, hertz, milleseconds)
  tone(buzzer, 262, 417); // C4

  tone(buzzer, 349, 417); // F4
  delay(x);
  tone(buzzer, 349, 208); // F4
  delay(x/2); // Give the feel of a eighth note rather than quater
