the best way to PMW an led strip with an arduino

[gonadgranny]

Hi all. I have just purchased an led strip which is 2A, 24W. I was wondering what would be the best way to PMW it with an arduino.
Thanks,
Danny

You might try a motor driver shield that can handle 2 amps, with an external (12v ?) power supply.

Thanks. Could a mosfet be used?

Yes. Heres a link to a you tube video on using a mosfet to control a 12 volt LED strip.

Led strips can run up to 14.2 V for cars with more power or nominal at 12V

Connect V+ and switch V- to gnd using ANY "logic level" gate drive N-ch Mosfet with RdsOn<=50 mOhm for <= 1/4W dissipation and <=100mV drop.
