Final Product

Problem fixed and run quite well. Let's take a look how Noise Pollution Index is made. But I still found that some components cannot be well plugged like the microphone and so on. The data are not well-received (i.e. by chance! XD)

Finally done! But still needa fix it!

Finally, Noise Pollution Index was a wrap on 23/4 and presented. But there is still some problems of the use of the amplifing sound circuit because it doesn't work! I need to try again on fixing the complicated circuit or simply just use the external power (i.e. not powered by Arduino) with or without the amplifiing circuit.

Let's see the presentation LIVE!

Something get stuck!!!!

Oh my god! There is something get stuck when I try to fix the problem of storing the sound files. I found that it is out of my ability to do it (either using a breakout board with microSD card player or using a recording board). So, I have decided to change my project which is simplier and more interesting. Let's take a look at my proposal.

I'm Loving Arduino! (though needs programming!!!)
