hi everyone,
i have mg996 servo connected to 6v and ardiuno nano connected to 12v with vin pin and gnd common for both arduino and servo
but servo doesn't work till servo positive is also connected to ardiuno 5v pin also, otherwise it doesn't move...
where i am going wrong?
Have you tried powering the servo on a separate 5V power, not from the Arduino?
yes, thats what i want to do, till i don't connect even positive to 5v it doesnt move...
Can the source of the 6V deliver enough current to power the servo?

i tried same power source reduced to 5v and connected both ardiuno e servo to only one power source and it works... but i want to give servo 6v seperate and ardiuno seperately.
Just connect a 6volt supply to the servo and to the V-in pin of the (classic) Nano.
The 5volt rail of the Nano might not be exactly 5volt, but that doesn't matter in most cases.
It normally runs on about 4.6volt when powered from USB anyway.

i want to connect the separately as when connected together arduino restarts when load is high on servo (i mean if servo blocks arduino restarts and throw servo down) but if connected separately this doesn't happen..
thanks btw
The grounds must be connected so that there is a return path for the servo control signal.
Post a schematic showing how everything is connected, please.
Here is how it should be:
A MG996 draws a stall current of 2.5 Amp at 6volt. If the supply can't deliver that without collapsing, then it might indeed be better to give the Arduino it's own supply.

thats what i am trying to do, servo connected to 6v 5amps power supply and arduino to 12v with negative common... but it doenst work till positive of servo is also connected to arduino 5v
Disconnect the Nano from the setup. Feed it with your 12V source on Vin. Do you get 5V on the 5V pin?
yes, i do get 5v from that pin...
12volt on V-in of a classic Nano is in the danger zone. You can't power much else from it at that high voltage. Powering the Nano from a 5volt cellphone charger connected to the USB socket would be a lot safer.

thanks for advice, but my issue is not of nano protection but to not give common power source for both as i want to give 6 volt to servo and arduino 5v or 12v separately
but my servo doesnt move if positive is not connected with nano
Show us how you have wired it up.
Use 5V (regulated, applied to the "5V" pin), not 12V.
ok, i have followed as you people were saying... regulated 5v to arduino 5v pin
negative is common but power source is different
please advice.. thanks
