İs there any way different way than GND's Arduino
Dario,

There are only 3 ground pins on the Arduino Uno, but don't be afraid to "breakout" these pins with wire. It doesn't matter if you connect multiple component grounds together, as long as they are connected to ground with no resistance between them, the circuit will close. 

Strip board and pin headers will help you here, try this: http://www.instructables.com/id/Home-Made-Arduino-Prototype-Shield/
