Hi there i would like too combine the two codes if it is possible :? ?? so when the infra-red proximity sensor is triggered the piezo speaker  will play a simple melody   smiley-grin

is it possible to combine these two codes??
Code:
const int speakerPin =  13;      // the number of the speaker pin

int sensorValue; //integer used to calculate distance 
int distance; //real distance in cm obtained from the formula (4800/sensorValue -20)
int sensorPin = A0; //Sensor is connected to Analog 0 

void setup()
{
  Serial.begin(9600); //initialise serial port
}

void loop()
{
  //read sensor value
  sensorValue=analogRead(sensorPin);

  //formula required to calculate the 
  //exact distance from the sensor.
  //Taken from Phidgets datasheet
  distance=(4800/(sensorValue-20)); 

  //Serial.println (sensorValue); uncomment if you want to check the sensorValue read from the IF sensor
  Serial.println(distance); //print the value onto serial

  if (distance <=60){
    digitalWrite(speakerPin, HIGH);
  }
  else {
    digitalWrite(speakerPin, LOW);

  }
}


AND the Tone Melody code

Code:
/*
  Melody
 
 Plays a melody
 
 */
 #include "pitches.h"

// notes in the melody:
int melody[] = {
  NOTE_C4, NOTE_G3,NOTE_G3, NOTE_A3, NOTE_G3,0, NOTE_B3, NOTE_C4};

// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
  4, 8, 8, 4,4,4,4,4 };

void setup() {
  // iterate over the notes of the melody:
  for (int thisNote = 0; thisNote < 8; thisNote++) {

    // to calculate the note duration, take one second
    // divided by the note type.
    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
    int noteDuration = 1000/noteDurations[thisNote];
    tone(8, melody[thisNote],noteDuration);

    // to distinguish the notes, set a minimum time between them.
    // the note's duration + 30% seems to work well:
    int pauseBetweenNotes = noteDuration * 1.30;
    delay(pauseBetweenNotes);
    // stop the tone playing:
    noTone(8);
  }
}

void loop() {
  // no need to repeat the melody.
}


looking forward to hearing from someone that can crack this for me  smiley-grin  smiley-grin  smiley-grin  :?
