Yes I know it uses the electromagnetic fields but how is the circuit made? I'm a newbie and is quite unsure how to do these kind of things...

Hi..

I'm trying to build a simple Theremin like thing and has tryed to so by building a capasitor but I have failed.
I tryed this but it didn't work..

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1171076259

Can anyone help me on how to do such a thing that reacts on your body without one touching it - Don't need it to play music just get the signals in..

I'm new to Arduino and code..

Thank you for your time

I got this error when I exported to the board::

What can this mean?

I'm not sure I understand the last part you write.. But I tryed using pin13 and the small LED blinks..  smiley
How would I print the exact signal/numbers that is recieved - I need to use these numbers..

Thanx again

I fixed the problem with size.. Was working in an old version of Arduino - so now it's no prob.
But I don't seem to get any signal, numbers or anything out..

What could be the problem?

Thanx for your time

So what can I do about  that? I'm really newbie to this.. Learning as I go..

Thanx for your time and help

Looks cool.. :-)

And thanx for the help so far.. But I have one problem and that is that the file is to big to fit on the Arduino board. Why can this be??

I will tell you more about the process of the project later...

Thanx

Hi

I've been trying to do this but I can't get it to work.. Wired everything up as on the photo and then ran the program but nothing happened. Can you give a description on how to do this currectly since I apperently do something wrong.

thanx
