I use this: https://copy.com/thumbs_public/brrTUR3NBIZp/2.+DIY+Piano/2.+DIY+Piano+%28Breadboard%29.png?size=1024 I have a problem reading the data. Do not get anything. How to wire touch it nothing happens, I do not know what is wrong. Variables total1, total2, total3 always have the value 0. My code
