You don't need limiting resistors for MOSFETs. Try it without them.
I am trying to control some LED strip lights (12V, 2 AMP) with the arduino and am trying to select the correct MOSFET to handle the load. I thought this one (http://www.vishay.com/docs/91325/sihlz14.pdf) might work but it does not. When connected with all the pull down and limiting resistors, the lights are dim. Then I noticed when I connected the Drain to Source without the gate power was getting through and dimly lighting the lights...I have researched several sites and similar projects but they do not have the same conditions. Any thoughts? Thanks community!
