How do I connect this electret microphone to the Arduino?

Thanks!

The idea is to amplify the signal from the microphone, which is in the millivolt range, to a level in the 0..5V range, that can be converted by an analog input of Arduino.
On the same page you referenced (sparkfun), click on the "Example Audio LED" link, and it will lead you here:

Schematics, board, explanations are all there.
Let us know how you progress with this project :slight_smile:

Thanks for replying.

I actually realized that I bought the electret microphone which needs to be plugged into a huge circuit before it can actually be read by the Arduino.

The link is here: Microphone \ Learning \ Wiring

So instead of wiring the whole thing myself... I am going to buy: SparkFun Electret Microphone Breakout - BOB-12758 - SparkFun Electronics so I can wire it like this: ElectretMicrophone \ Learning \ Wiring

Thanks for the help though!
