Capacitive sensor- how can I read it?

Hi,

another depressingly nooby question i'm afraid. I'm trying to follow this suggestion:
http://www.arduino.cc/playground/Code/CapacitiveSensor

I managed to get the code uploaded onto the arduino and attach a wire attached to a piece of foil onto digital pin 9. Which is great. But how can I see what kind of response i'm getting? how can i make it do something? a read-out on the screen even? i'd love to trigger an audio file when the user's hand gets close to the foil. Any hints would be great!

Hi,

the sample code should output information on the serial port. After uploading you can open the serial monitor (the most right button in the toolbar) and the you should see output.

regards, toby
