Description
Part of a larger project. This uses an Arduino Micro to control a LED light strip.Video:

LED light strip (cheaper at Costco):

Digi-Key MPS650GOS-ND (TRANS NPN SS 2A 40V TO92)
Digi-Key 811-2196-5-ND (CONV DC/DC 7.5W 36VIN 5VOUT)
Breadboard, 22-gauge solid wire from Radio Shack. Battery holder from either Radio Shack or Frys.
Notes: The LED light strip normally takes 12V and requires more current than the arduino PWM outputs can supply. So I used the transistors in open-collector configuration to supply the higher voltage (actually around 10V) and current needed.
The program in the arduino is straightforward, every 50mSec it assigns the red PWM output to a random value between 0x40 and 0xff, the green PWM output to a random value between 0x0 and 0x8, and the blue PWM output to a random value between 0x0 and 0x10.
