MB-102 and servo motor problem

Hello lads,

I got a problem with my MB-102 and servos. I am using Nano as micro controller unit. As you can see, i am connecting my Nano to servo motor through D9 pin and i am powering Nano with USB cable from my computer. I am connecting VCC and GND pins of servo motor to MB-102 and MB-102 is connected to electricity adapter.

I just can not make servo motor move.

I found a solution at reddit but didn't understand the solution. They say:

Question - did you connected the grounds together
Answer - It worked, thanks a lot!

How do i have to make the wirings to make this basic module work? Do i have to connect MB-102 GND to my Nano? Or even both GND and VCC to Nano? Can you please help me? Here is the fritzing drawing.

Thank you in advance,

Just the ground. Reason is, the signal from the nano to the servo on the yellow needs a 0V to measure against, else what you have is like one hand clapping.

In pic, I showed in blue. (I don't know which nano pin is gnd :wink: )
