Topic: Arduino Uno - Which Ground Pin? (Read 4197 times) previous topic - next topic

Hi Guys,

My current project includes 8 servos and an external 6V battery. I know I need a common ground so that the signal can actually be sent from the arduino to the servo control lines. My question is which ground pin on the arduino uno should I use? Does it matter?

Thanks,

Mike

No, you can connect it on any ground pin, they're all the same ground.

It does not matter.
Use any one.
