IS this circuit not grounded?

Hello, I drew the keys with the graphite and successfully uploaded the sketch onto the arduino uno. I have the patch in Max open but I don't know what to do next. How can I get Max to work with the Arduino?

Hi i like the idea and tried to make it but the arduino displays a lot of noise. Other tutorials sugested an pull-up resistor of 1M, did you use this as well? In one of your pictures i see some resistors but you did not mention them, are they necessary?

What extra-softwares does it requires to work on PC? Can you point that? I'm looking to do it, but I unfortunatelly don't own a Mac...
