外接的电源是什么方法呢？用三极管扩流吗？看了下楼主提供的网页，直接下图这样接线就可以了吧？
On the ATX power supply, short the green wire on the 24 pin connector to one of the black wires on the same connector, and that will make the power supply turn on. Plug it in and test that it comes on.
Check the voltage across a red and black line coming out of the power supply, it should provide +5v dc. Turn off your power supply. Connect the above-mentioned lines to the red and black wires on the light strip, (which are labeled +5V and GND where it connects to the light strip, in tiny typeface.)
Connect the blue line from the light strip, (which connects to the LED strip at the point labeled DIN), to pin 6 on your Arduino. Connect the black line from the LED strip to the Ground pin on your Arduino.
