External Power

So I did some reading and some internet searching, and think I have at least part of the power issue figured out. I purchased a 7805 +5VDC Voltage Regulator, wired up my 1/2 size breadboard as my external power supply and added an led to that board and to 3 others down the line as a visual to see if power is being routed properly. Now with just the ground from the Arduino going into the circuit I can get everything operating properly. So the next test will be to get a Voltage Regulator with a higher current rating and a heat sink to get up to the current I need to drive all of the leds. 2 internet posts that helped a bunch. *ITP Physical Computing & *http://pixelriot.com/pmatp/node/285
