 Bigger Bigger  Smaller Smaller  Reset Reset

Hello Community,

I recently bought this at my local Radio Shack:
http://www.radioshack.com/product/index.jsp?productId=16306856&clickId=489254786&affiliateId=59782&affiliateCustomId=#

I'm a bit confused with this LED strip as it only has 3 Wires coming of it. I think it's 12v, GNG and Data. Does anyone know how I would wire this with an arduino?

Thanks!

Look at that chip U4. What type does it say it is?
Then look up that for using with the arduino.

It is a serial protocol where you send data by waggling the data line to control each of the colored LEDs.

As the LED strip continues each chip & led is incremented. I have U1 -> U5.

Yes I know but all the chips are the same.
You talk to them with a protocol.

What that protocol is depends on the type of chip you have.
If you are not going to tell what type of chip you have then the only chance I have of helping you is if I actually buy that strip myself and look at the chip.

That is not going to happen.

I've found the type of chip. This strip has poor documentation. I'm working with a TM1803 v2.

I'll post back with what ever information I manage to find. I appreciate your help.

Thank you very much for your help.

Looks like I have some timing issues to work out.

I have the same LED strip. Have you gotten anything else figured out?

At the RadioShack link there are hotlinks to a ZIP with PDEs and the datasheet for the strip's controller and there's a PDF, too. 
It's the "Product Summary" tab, "Downloadable content" (they aren't highlighted - probably so as not to call attention to them and keep consternation and anxiety stoked.)
You have to make a folder to put each of the PDEs into.
I've attached the ZIP and the PDF to this post.
