    Playing Wave file using arduino

    Hello, I really liked this project. Right now I'm doing a piano with Arduino Mega 2560, and I'll use 12 buttons for the keys. Can I use the same 22k ohms resistors to 12 buttons? It works only with 2 pins connected, the 3rd pin no longer plays. If you don't fully understand what I ask, I apologize for my English.
