This is a project let you sleep better at night, rely on the slow version Christmas song on the eye mask.

Step 1: Prepare Materials

Materials

1. Arduino Leonardo

2. Electronic Material Horn

3. Eye mask (the one you prefer the most)

Step 2: Build Up

Build up your Arduino Leonardo Board

Put the Electronic Material Horn directly on the place I drew

(Make sure it won't move around)

Step 3: Time for Program

This is the time for program, open your "Arduino" on your laptop and directly copy the program down here.

int buzzerPin = 13;
int tempo = 200; char notes[] = "eeeeeeegcde fffffeeeeddedg"; int duration[] = {1, 1, 2, 1, 1, 2, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2};

void playTheShit(char note, int duration) { char notesName[] = { 'c', 'd', 'e', 'f', 'g' }; int tones[] = { 261, 293, 329, 349, 392 };

for (int i = 0; i < sizeof(tones); i++) { // Bind the note took from the char array to the array notesName if (note == notesName[i]) { // Bind the notesName to tones tone(buzzerPin, tones[i], duration); } } }

void setup() { pinMode(buzzerPin, OUTPUT); }

void loop() { // Scan each char from "notes" for (int i = 0; i <= sizeof(notes)-1; i++) { if (notes[i] == ' ') { // If find a space it rests delay(duration[i] * tempo); } else { playTheShit(notes[i], duration[i] * tempo); }

// Pauses between notes delay((tempo*2)*duration[i]); } }
