Mosfet HSS3N10 with arduino

You couldn't find a more exotical FET - why not use one of our most 
common parts IRLZ34, IRLZ44 or IRF3708?

Your circuit will not work properly, because R1-R2 will divide the 
gate-voltage.
For R2 use 100k instead of 3k. For faster switching, also reduce R1 to 
270R.

Mainly wrong.
LED has no cirrent limitig device in series (resistor or current 
tegulator).

HSS3N10 gets only 3V on Gate. This is UGS(th) where the transistor turns 
OFF.

It is an unneccesary 100V type.

Use IRLML2502 and make R1 100R, R2 10k.

With these resistor values even the HSS3N10 may be used, as it is 
specified for 4.5V with 0.3 ohms which carry 0.35A without problems.

R1 = max 100R
Check, if there was a current limitation included on the LED. Otherwise 
you need a current source or at least a limiting resistor in series with 
the LED.
