Hello people,

on my arduino I can find the 'GND' label three times: http://arduino.cc/en/uploads/Main/ArduinoADK_R3_Front.jpg
- two side by side on the lower edge between 5V and Vin
- one of the upper edge between AREF and digital pin 13

I guess the upper GND is the groud for the digital signal pins.
The two lower GND's are the ground for each 3.3V and 5V ?

But which one is for 3.3V and which one for 5V, if so?

I appreciate any help. Thanks in adivse, yours
Murat

They are all connected. It doesn't matter which you use.

The GNDs are common. They are all connected and can all be used for either 5V or 3.3V.
