Well it seems I have hit a speed bump today using this method.
It is OK however because I have developed another method using resistors that I will go into more detail about soon. Let me just post some pictures of what I have been up to.
I will post a more in depth explanation as to this setup soon. While testing out the strings with the Arduino, I discovered that I was unable to hold down more than one note at once. If I held down a chord my resistance readings would go haywire. I do not want to design a monophonic instrument.
