How to Interface Electrate - Condenser Microphone

Hey Guys,
I am trying to use Electrate - Condenser Microphone as sound sensor which can help me acting as a switch for turning on LED.
The project is like Clap Switch. Would you please tell me how to interface it?
I tried searching on Arduino but couldn't find the answers.
My hypothetical algorithm is:
1)Use Pin Analog Pin # 0,1 as input for the sound.
2)Connect a LED to Digital O/P Pin #2,3.

So what will be the program as per the basis.?
Thank You.

Connect the microphone up with the circuit you find at the front end of here:-

You then need at add a capacitor to the input to make it act like an envelope follower. Start with a 0.1uF.

Then read the analogue input and turn on the light if it is above a threshold. Look at learning section for inspiration / information
