 Bigger Bigger  Smaller Smaller  Reset Reset

Hello,

I've got the arduino board and a few of the LED light bars from Sparkfun. These are the bars w/ 3 bright LEDs packaged up w/ limiting resistors and protection diods --- they absorb 30mA at 12volts. So, I've got 6 of these things I'd like to control w/ the arduino with full dimming ability.. I've been away from basic electronics long enought to not be sure how to approach this. Any help would be greatly appreciated.

Would I use a mosfet to take the load controlled off of the PWM port of the arduino board? How exactly should I go about this?

Thanks!!

I did something similar with another uC and 10 V (12V supply).
Probably you can use this.
