Hey, I'm wondering how I can control a 59 LED strip with 4 pins (12V, R, G and B pins... yes, it was a cheap one )
I currently do not own an Arduino, but I am hoping to buy an Arduino Nano, and I have very little C and C++ language knowledge, so I'm gonna be a huge script kiddie here).
It's a 15€ EGLO 3 Meter LED strip... If anyone need more information ask me and I'll give it.
Thanks in advance.
(side note here, I am not a native English speaker, so sorry for any mistakes)
More information (such as, say, a model number) would be nice.
A link to a web page or to a data sheet would be even better.

I didn't give that information because I was unable to find the box it came in, but after a lot of research (AKA googleing, giving up, and going to the store I bought them in and find the very same model), I found out it is an EGLO 13532 (You can find information everywhere but on EGLO's website for some wierd reason, and I tried finding a data sheet for it, but I couldn't find it, but I noted down some information from the box which are the following:
Max 13,5 Watts
Max 250 lumen
Input Voltage: 100-240V ~ 50-60Hz
Output Voltage: 12V DC
mA: 1100mA
Lifetime: 25.000h
IP20 (whatever that means)
If you couldn't tell, it comes with a transformer with an integrated IR controler that has the following specs:
Input Voltage: DC12V
Output Current: 3x1A
and has, with my extremely great type-drawing skills a scheme that goes something like
(-)-----(o-----(+)
So what do you mean by "control"?
The entire strip will be a single color. I do not believe that you can control the 59 individual LEDs independently.
You will need transistors (at least three of them) to control the individual colors. The Arduino will not handle that much current by itself. The Arduino cannot directly handle 12V either.
These LEDs will need resistors or something to control the current. It is completely unclear to me where these are located.
There may already be an existing shield that can do this task.
By the way, the information that I was able to find describes this as a 20W 90 LED strip. This is different from the 13.5W and 59 LEDs that you describe. I am confused.
The information I gave you came straight out of the box, except for the LED count, as I split the strip so it fits my desk... I am going to upload a picture of the rest of the disconnected LED strip to imgur so you can see the strip for yourself and I'll link it ASAP
here's the link Imgur: The magic of the Internet
Edit: And by control I mean be able to change the color to custom values impossible to achieve with the IR controler due to it's limitations, as it only alows for preset colors, strobe, fade, flash and "smooth" mode
It seems that you need https://ledshield.wordpress.com/ or equivalent. Good Luck!
