After I refered some melody codes,I wrote a melody code and connected with the arduino board. Now the first phase is done but as I have mentioned above I wanted to integrate the speaker with the potentiometer so I did that well that's good but still the potentiometer is not worked as I wanted.Hope I will fix that sometime later.</font></p></h4> <img src="speakercode.JPG" alt="spe" align="center"width="700"height="600"> <p align=center><object style="height: 390px; width: 640px"><param name="movie" value="http://www.youtube.com/v/K1BQCIMoSLc?version=3&feature=player_detailpage"><param name="allowFullScreen" value="true"><param name="allowScriptAccess" value="always"><embed src="http://www.youtube.com/v/K1BQCIMoSLc?version=3&feature=player_detailpage" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="500" height="300"></object><font color="white"></font></p> <p align=center><font color="black">Here is what I did and uploded on youtube so that I linked it with my page.</font></p> <h3><p align="center"></p></h3> <h3><p align= </p></h3> <p align=justify><font color="white">. </font></p> <a href="http://www.facebook.com/"><img src="facebook.jpg" align="right"width="30" height="30"> </a> <a href="http://www.youtube.com/"><img src="youtube.jpg" align="right"width="30" height="30"> </a> <a href="http://www.twitter.com/"><img src="twitter.jpg" align="right"width="30" height="30"> </a> </td> </tr> <tr> <td style="background-color:#ff0000;text-align:center;"> Copyright © 2012 habtamu. g</td> </tr> </table> </body> </html>
