CrossRoads:
MOSFET works similar to NPN (2N2222).
Arduino drives a voltage into the Gate thru 150 ohm resistor, (like R1),
Source connects to Gnd,
Drain connects to the 'bottom' of the motor.
Rds of the MOSFET is very low, so the motor will see almost all of the battery voltage, vs the NPN wasting 0.7V across the Collector-emitter.
Very interesting, i will try it, and will update the topic with the results, thanks for the help once again
I didn't know there was a "Resolutions" toolbutton.
That's a new one in me, but then I'm so old, everything is new to me. I went out to my car this morning and it looked new to me. All I did was wash it last week and it still looks new. Must be the rain here in California doing that. Beats ice and snow...

The NPN won't waste 0.7V in saturation, 0.1V more likely. 0.7V is the base-emitter voltage.

is there any alternative MOSFET to IRL? i would have to import it, and takes to long lol
Check the MOSFET which you already have, you need a switching mosfet, in data sheet look for threshold voltage less than 5V.
example - IRF540
Gate-Source Threshold Voltage VGS(th) VDS = VGS, ID = 250 μA 2.0 - 4.0 V

Yeah i see it: Min 2.0 max 4.0. But i still don't follow, i was told this isnt a logic level MOSFET, therefore i couldnt switch it to what i wanted, and i was looking all around me and far for it and nothing. So, you're saying i could do it with a IRF? im confused
