Re: Powering Arduino
We have used this module from Sparkfun for 12V->5V for our Arduino and LEDs..

You need to calculate the value of an external resistor for your output voltage (check the datasheet), but it's easy to use and a high current rating. May need active cooling depending on the current you draw - it does get pretty warm with our LEDs.
