I have an arduino project that is almost finished.
Now it controls a series of ShiftBrites(ShiftBrties being 10bit RGB LED's) now they use a simple 4 wire configuration(Data, Logic, Clock, Enable) and +5v and GND. its all done over a wireless setup. ShiftBrites are connected to a Arduino and an xBee module. (My basic setup http://ashleyhughesarduino.wordpress.com/2010/08/01/shiftbrites-and-the-arduino/)
The Problem is that the arduino can only output so much juice(Current) before everything starts smoking, my question is how would I connect it up so that the +5v comes straight off the power pack from the wall?
Connect to the Vin point on the arduino? or Connect the +5v before the arduino? ???
