A small test to make node drive a 32-led rgb strip as seen here: http://www.coolcomponents.co.uk/catalog/strip-ledm-addressable-p-706.html Code mostly translated from this example: http://www.sparkfun.com/datasheets/Components/LED/LED_Strip_Example.pde Update: Difficulty driving the led array with only the first led lighting up. This: http://learn.adafruit.com/light-painting-with-raspberry-pi/hardware suggests that powering the raspberry from usb is a surefire way of nuking it. Basically the LED's draw more power than the usb port can pump through.
