If you want use it with a microcontroller, you would need an n-channel mosfet <a href="https://www.sparkfun.com/products/10213" rel="nofollow">https://www.sparkfun.com/products/10213</a> to turn it on and off. The LED strips require a lot of power (especially the 5M strips) but it worked good with my variable power supply set s 12V/1A. The LED strip does get warm to the touch when using.</p>

I believe the circuit is identical to this one shown on Adafruit except that it has a 150-ohm resistor instead of a 130-ohm one for the blue and green LEDs: http://learn.adafruit.com/rgb-led-strips/schematic<p>On paper, giving the strip 12V and grounding the other three pins should result in a current of 20mA through each red LED and 18mA through each blue and green LED, totaling 56mA per group of 3 RGB LEDs. Since there are 20 groups of 3 RGB LEDs per meter, the current should be 1.12A per meter and 5.6A per 5-meter strip.</p><p>I tested a small strip to see if my numbers were close. I put 12V on a strip that was 6 groups long, and it drew 300mA, which comes out to 50mA per group (11% less than expected).</p><p>Summary:</p><p>expected current @12V = 56 mA/group, 1.12 A/m, 5.6 A/strip</p><p>measured current @12V = 50 mA/group, 1.00 A/m, 5.0 A/strip</p></p>

I tested them with a large lead acid battery producing 12.65V. I found the following<p>When individually connected the draw was the following
Red: 1.6 Amps
Green: 1.4 Amps

The addressable ones tend to require slightly more beefy power supplies while running off of 5V - a computer PSU might be a good match there.</p></p>

I assume that the requirements for current will be significant, and not just any power supply will make the cut.</p>
