Getting LED strips to work with Raspberry Pi

Notice the 50Ohm: or you may be buroning off the LED/.

Running a 32-LED strip:

To quote from above:

Instead of supplying power to the Raspberry Pi’s Micro USB connector, a 5 Volt DC power supply is required because the LED strip draws significantly more current than the USB input can provide. A 2 Amp power supply is sufficient for a 1 meter LED strip, while our larger 10 Amp supply can power up to 5 meters of LED strip (plus the Raspberry Pi board, in both situations).

+5V and ground from the power supply connect to the 5V and GND pins on both the LED strip and the Raspberry Pi GPIO header.
