I would like to use the following LED strip https://www.sparkfun.com/products/12027 with an arduino UNO, my goal is to have two 1 m LED strips controlled by the arduino. THe strips are 5v and each LED needs around 20 mA, since each strip has 60 LED it would be necessary to have 120 * 20 mA of current. Now I realize that the arduino UNO would burn out powering this so I was looking at the following 5VDC 3A power supply http://www.robotshop.com/en/5vdc-3a-wall-adapter-power-supply.html.
Ideally I would also want this power supply to also power the arduino, however I read that the uno need 9-12 v in and therefore this power supply would not work. Is there a way I can do this so it works on just the one power supply, or should I use the 5VDC 3A for the LEDs and have a battery for the arduino?
