とりあえず起動音

Arduino misc


こんなんばっかですみません。 m(_ _)m


とりあえずこんな感じで。

/*

pipo2 / Arduino22


Arranged by OkibWorksLabo 2011/06/17

 The circuit:
 * Speaker attached from pin 14 to ground (thru ~1K resistor as needs)
 * pushbutton attached to pin 2 from GND

 */

int buttonState = 0;

const int pushBtn =   2;
const int soundpin =   14;

void setup()
{
  pinMode(pushBtn, INPUT); 
  digitalWrite(pushBtn, HIGH);

  pipo();
}

void loop()
{
  buttonState = digitalRead(pushBtn);

  if(buttonState == LOW) {
    pipo();
  }
}

void pipo()
{
    tone(soundpin, 4000);
      delay(100);
    tone(soundpin, 2000);
      delay(100);
    noTone(soundpin);
      delay(20);
}

起動時に 1回「ぴぽ」言うて、そのあとは digital 2ピンを LOW に落とすと鳴ります。
