Sound input to control my internet

Hi everyone!

First post here, so excuse my lack of knowledge. We all have to start somewhere, hehe. I have just aquired an Arduino Uno with some accesories. I have done the blinking LEDs, displaying analog input and the other "new-to-arduino"-projects, but am about to embarge on my first real project.

It is for my design research class, where our task is to make a digital phenomenon to analog. I have decided to take the concept of internet access, something we all take for granted and never really think about, and use analog input to control it.

So here is my project. Use a microphone on the Arduino, send that data to the computer, and make sound control whether or not the internet is on. This will all be packed into a nice little box, with LED-indicators showing the decibel amount (see attachment)

I am expecting the microphone by this week, but in the meantime I have made a demo with a light sensor getting input and outputting it to the LEDs.

So basically what I need help to, or check if it is feasable, is the internet access. How would I make an input control the internet? Can this be done in the Arduino platform or do I need to learn programming? I do not have much knowledge about scripting and stuff.

Thank you for all help!
