Very beginner with this.

I am powering an analog LED strip (10 sections, total 12 V, 200 mA required). I'm using a nN-mosfitMOSFET and an arduino to fade in/out the lights. From my calculations I don't need a resistor, but I feel weird about this (I haven't seen a schematic without a resistor). Is it okay to not have a resistor?

There is 11V coming from the VIN pin on my arduino, and since I need a max of 12V then I wouldn't need a resistor? And you don't use a resistor for amps, since the device will only pull what it needs.

Here is a picture of my setup ( which works, I'm just worried there is something I'm missing)

Any advice would be tops!

My LED strip arduino setup doesn't use a resistor. Is that okay?
