İ'm making a project on my arduino uno when i figured out i had no more GND left to finish the circuit. İs there any other way to optimize, use pins as input maybe. İ tried whit other websites, however, they weren't much of a use. Can you show an example also.
Thank you sooo much in advance,
Dario

Can't you just connect multiple GND wires to one GND on the board?Pawel– Pawel2016年01月16日 21:50:09 +00:00Commented Jan 16, 2016 at 21:50

No, two wires don't fit into one slotDouglas Maron– Douglas Maron2016年01月16日 21:51:58 +00:00Commented Jan 16, 2016 at 21:51

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/
