I want to connect my motor to vin pin, but my motor draw 0.95A starting current and 400mA continous current. Does the vin pin is able to satisfy this current? what is the max current of this pin?
The arduino is powered by power supply of 12V 1A.
This is the circuit if someone didn't understand:
As the name of the pin suggests, VIN is an input.
But besides that, no pin of the Arduino is capable of sourcing 1A.

How Vin is an input? i don't connect to there anything.
so how could i satisfy 0.95A to the motor using the power supply of the arduino?

Both wrong.
Vin is a supply pin. It can therefore be output as well as input.
Arduinos with DC sockets (Uno/Mega) have a ~1Amp reverse protection diode between DC jack and Vin.
So you could draw ~1Amp from the Vin pin.
Not very wise to use a motor on that pin without sufficient protection.
Maybe better to use a separate supply for the motor.
Leo..

But why? there is a flyback diode. it could be dangerous when the emf current discharge through that pin?
Don't use "V_in" (at all.)
@RunwayPancake - Thanks for the very useful diagram. I have bookmarked it.
