driving 12v led strip through arduino , which transistor ?


hello there ,
i wish make use of 12v ebay single color led strip, driving external 12v power adapter.
i'm famillar method of dimming , controlling strip transistor , wondering transistor should choose 5m strip ( consuming 1.3a 12v current ) , based on paramters should choose ? thank .

logic level n-channel mosfet low-side switch, choose 1 rds(on) < 0.1 ohm
for cool running.  make sure logic level.  use 150 ohm gate resistor or so.  make sure
the 12v supply decoupled @ mosfet, 100uf 16v electrolytic or bigger, will
reduce interference generated.

low side switch means +12v strip's +12v wire, strips 0v/gnd wire drain of mosfet,
source of mosfet actual ground (of 12v supply , arduino gnd - must commoned).
