11. Piezo Buzzer - Spark Core

Buzzer would be useful in some cases, so let’s learn how to use it.
I started using Fritzing to draw how I connect things.

And code is below

// Turn on/off Piezo Buzzar
//  

void setup() {
  Serial.begin(9600);
  pinMode(A0, OUTPUT);
}

void loop() {
  delay(1000);
  analogWrite(A0, 2000);
  delay(100);
  analogWrite(A0, 0);
}
