Electret Microphone

Thanks alot that's what did it! Also another question. on all forums i've read, when an input is given to the electret microphone, the value on the serial reader should go down (usually around 860 and the 750-800 when blown on) how ever with this set up, im getting about 136 when its in a silent room and it actually spikes up to about 900 when blown on lightly. When its receiving input, is it increasing it's impedance?
