Program description

• Function
  • "playNote()" Volume control
  • "colorSet()" Color control
  • "blink()" Judge if the key is pressed
• Define pin

#define PIXEL_PIN    A0 //Colored led 

int key_Pin = 2;  //Key 
int speakerPin = 6;  //Buzzer

• Check switch and see if it is pressed.
  • Use file " key_get(key_Pin, 0)" to detect if the key is pressed. " key_Pin " is the pin that connects with the key, which can be change by users. "0" means triggering once pressing the key. "1" means triggering after you press and loosen the key.
  • Each time the key is detected to be "pressed", the True and False values of " play_pause " will change once. Therefore, you can control the music and light according to the values of "play_pause".

void blink()
{
  if (key_get(key_Pin, 0))  //Press the key 
  {
    delay(200);  //Shockproof 
    play_pause = !play_pause; // Status changes one time. 
  }
}

• Light change (Red-green-blue-yellow)
  • "colorSet(strip.Color(R, G,B));" R, G and B are three primary colors. Users can change that according to personal needs.

add++;
if (add == 5)
add = 1;
if (add == 1)
colorSet(strip.Color(i * 10, 0, 0));
else if (add == 2)
colorSet(strip.Color(0, i * 10, 0));
else if (add == 3)
colorSet(strip.Color(0, 0, i * 10));
else if (add == 4)
colorSet(strip.Color(i * 10, i * 10, 0));

• Play music
  • Save fixed notes and change the pitch in program definition.

int notes[] = {
  NOTE_C4, NOTE_C4, NOTE_D4, NOTE_C4, NOTE_F4, NOTE_E4,
  NOTE_C4, NOTE_C4, NOTE_D4, NOTE_C4, NOTE_G4, NOTE_F4,
  NOTE_C4, NOTE_C4, NOTE_C5, NOTE_A4, NOTE_F4, NOTE_E4, NOTE_D4,
  NOTE_AS4, NOTE_AS4, NOTE_A4, NOTE_F4, NOTE_G4, NOTE_F4
};
