RGB strip lights?
CoryBee:
Thanks for that info Mysterioii. :applaud: The white ones are Non-Addressable (not like they need anything else) and the RGB ones I got are addressable. I saw a demonstration of this model on youtube.
Mysterioii:
If you google around there is lots of info on driving those strips with microcontrollers like Arduino. Catch is, there are different driver chips that use different communication protocols and they are not remotely interchangeable. So you'll need to determine which chip is used in your addressable strips and find the appropriate code examples.
Can you send me a link to where you found 5m RGB addressable strips on ebay for $12? The 5m non-addressable ones typically go for $20-ish and the 5m addressable ones are often in the $80 range. Beware of bait-and-switch... I get a lot of components from China and usually have no problems but have had some mixed luck with the strips. The first time I tried out Alibaba, I ordered a 5m addressable strip for like $75. I was sent a 5m non-addressable one... and it had a few dead "pixels" to boot. >:S The seller insisted it was the same item as pictured (not remotely) and initially only offered an exchange if I paid the shipping to send it back... since I was already clearly getting scammed I was pretty sure he'd have my money AND his product back and I'd get nothing. Turns out Alibaba's customer support and dispute/fraud resolution is HORRIBLE compared to what we're used to. I took pictures of what I was shipped and linked to pictures on his listing, and they could see his snarky exchanges as I tried to straighten things out, and after MONTHS of back and forth all I got was a partial refund of like $20. Lesson learned, I will stick with ebay over Alibaba.... you may still get scammed but at least you'll get your money back.

Yea I messed with alibaba in the past as well, luckily only good things came of my experiences.
This was one of the images that was on the "auction"
So my assumption is it is addressable since there is different colors going a the same time. Picture could be lying, so we will see.
The white LED strip was a buy it now, the RGBs were regular auctions I caught at the end and sniped for them. Can always find some around $9 with 6min - 15min, wait for around 2 0seconds left on the clock and place a bid for like $13.51. 60% of the time, it works every time.

I used these RGB LED strips (non-addressable) with an LED-Wiz for cabinet lighting: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=221054249288
Here they are in action...
Mysterioii:
Ah I think what you have there is not addressable. Yeah I saw that style around quite a bit and almost got some of them, but what I think they are is RGB strips with separate LEDs for red, green and blue.
The non-addressable RGB strips I have use a single RGB led as a "pixel". I believe these strips have a red led followed by a green one followed by a blue one.... If you tell the strip to be "full blue" then I believe only every third LED will be lit up at all, whereas if it uses actual RGB leds then of course they'd all light up blue. This is fine, depending on the application. For underlighting it would be ok. The overall brightness and lighting density would not be as strong as if it used RGB leds.
I may be wrong of course, but I'm pretty sure I'm right. In the ones I looked at they would sometimes have a picture showing several colors, and if you looked real close you could see what I was talking about. In the pic you posted for example, it goes green on, red on, blue off, green on, red on, blue off....
Strips using separate LEDs for each color are cheaper than ones using integrated LEDs which are in turn cheaper than full-addressable LED strips.
I wouldn't say you got screwed or anything, especially for that price, but they may not be what you expect.
