Mate, third link down at the bottom is an amplifier... http://www.ebay.co.uk/itm/281169092289?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 thats the one I bought, pretty sure the one you said to lol
I have had a bit of a breakthrough though since. I plugged this one in straight through the A0 (http://www.ebay.co.uk/itm/191126721706?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649) and when adjusted, the green light that indicates input works perfectly, any low voice flashes the input light, exactly as I wish I could get the LED to flash. Picks up my voice from over 8 ft away so would be perfect for my box... Obv a better model than the original one I bought. Is there any coding that would allow the pin 13 LED to just copy that of the input light on the microphone? I have resistors, capacitors etc and really want it to flash at the same rate and intensity as the input light directly on the microphone, without having to obey any kind of threshold as I believe that would limit the light to being either on or off, and turn it on at a certain volume rather than have it adjust to the volume of the voice... I can post a vid of what I mean if you like, as I'm hoping there will be a simple code that can just copy the input, either using the amplifier or not either way...
Thanks again
