Can I control a 12V led strip (tm1804) with a 5V arduino?

And my strip has terminals: 12V+, GND, DIN and 12-.

Can anyone tell me what that the 12- is for? should it just be connected to GND?

Connect the strip to a 12V power supply (yes that 12- is GND), connect your Arduino to a 5V supply, make sure they both have a common ground, and you should be okay.

Thanks, looking forward to having a play with this. I just found the FastLED.cc website which has a lot of info too, before I only saw the old google code page.

Oh yeah, getting confused with Arduino.cc!
