Hi, how are you getting power to the WS2801 light strip?
If you are using the 5V pin on the adruino uno then it will not be enough current.
If you are using a separate power supply for the strip, have you got the negative of the supply connected to the negative/gnd of the arduino?
What is the voltage needed to run the strip.
