Introduction: Connect the Arduino and Make the Speaker Play

To make your Arduino to play a melody you need thes accessories.

One 5 ohm speaker

One Arduino uno board

One Push buttom

One 10 kohm resistor

8 leds

And a lot of core wires


Step 1: Connect the Arduino and Make the Speaker Play

This is how i connected the arduino to the white connection plate.
With these picture should help you get an ide of how to connect the speaker to the arduino plate and make it play the basic melody that you will find in the arduinio program on you pc.

Check out http://arduino.cc/en/Tutorial/Tone if you need more info on how to connect.
 

Step 2: The Code

/* Original code created 21 Jan 2010
/ modified 30 Aug 2011
/ by Tom Igoe (http://pastebin.com/tCYvfky9) and configured by me 2013 (my code below)
/
/ When you firgure out how to connect the arduino and made it play the basic melody. You should start coding
/
/ First of you will need the notes you can copy paste mine or just copy it from http://arduino.cc/en/Tutorial/Tone

//  The note duration in the melody for exampel 2 is the shortest and 8 is the longest:

    digitalWrite(melodyLed[thisNote], LOW);
    delay(pauseBetweenNotes);
    // stop the tone playing:
  
    noTone(8);
   
   
  } 

else {
//turn off sound
noTone(8);
}
 
}


Step 3: The Tone Function

Playing music in the arduino introduces a function known as tone(). This function controls your ability to play music. In the code it will look something like this:

tone(pin, frequency, duration)
or
tone(pin, frequency)

Where pin is the pin the speaker is hooked up to, frequency is the tone in hertz and duration is how long, in milliseconds.

If you use the 2nd convention, to stop the sound you must have a noTone() function.

noTone(pin)

In the previous step for the melody, you had to include the pitches.h file. This file just gives you a variable for every tuned note in hertz so you don't have to work out basic notes. This makes writing songs much easier!
