PWM, mosfet and LED strip


So i bought 3 IRL530NPBF and a Arduino Uno, and I´ve got 4,3m LED strip. There is resistors built in the led strip so i dont need any resistors to the strip, just 12v.

So I´ve tried connecting the LED strip´s GND to the drain and GND to source, and the arduino to the gate, as I was told. But nothing happens.. What am i doing wrong?

You've already asked in another thread.

Not about this

Sorry.. Dobble post then.. I didnt regonized it :D

But back to what you´ve asked in the other post. The LED strip got on wire to 12v and RGB is GND, so i connect the 12v to the powersupply and the RGB to the mosfets
