Hi Ruben,
Welcome to the Forums!
Connection of an RC servo is quite straight forward.
First connect a power supply to the servo, e.g. 3 or 4 AA battery cells.
Positive to the red wire, negative (ground) to the black wire.
Then connect a wire from the Netduino's ground to the servo's ground (the black wire or the negative battery terminal), and finally connect a wire from one of the Netduino's PWM outputs to the white wire of the servo.
Now power up the Netduino using your favourite method - USB, barrel, etc.
That's it.
The servo will not fry the Netduino because the white wire takes a low current digital signal, and the ground back to the Netduino just carries the same low current.
All the high currents are in the servo black and red wires connected to the batteries.
(I might have skipped the writing the software part.)
Have fun - Paul
