Hi Everybody,
I'm new to netduino. I've seen this topic discussed in the forum but couldn't find a good answer. So decided to ask.
I want to control a regular servo used in rc toys. This would be analog or digital servo with 4.8V - 6V power range.
As i understood the netduino will provide 3.3V. I'm thinking about providing the power from an external source.
Can somebody help me how to do that? Would i need to connect the + wire to my external power source, then the - from the external to the ground of netduino, and the signal of the servo to one of the PWM pins? I'm bit worried about the ground. wouldn't this fry the board? If somebody can show me photos or schematics of the wiring I would really appreciate!
Thanks,
Ruben
