I want to try to play around with arduino and led strips so I just ordered a 5050 LED RGB Strip
I know I also need a led driver for power but do I need anything else to control it from the arduino?
If I for example wanted to use a ultrasonic-range sensor to change the color of the strip depending of the sensor value, is this possible ?

Did you buy the RGB strip or the single color strip?

No.

Yes, if you purchased the RGB strip.
Hi,
For that kind of strip you will need 3 high current transistors, for example 3 high current, N-channel MOSFETS with logic-level gates. For example AOI514 (a favourite of CrossRoads) or STP16NF06L (which I have used in the past) and many other possible models (but before you buy, post the model you want to use so it can be checked).
Other than that, some 200~300R resistors to protect the Arduino pins and some 10K pull-up resistors (to 5V) on the MOSFET gates should be all you need.

I saw in one instructables that the author recomended using Mini Led Amplifiers
They only cost ~1,5$ would that be an good option?
In that case would I only need an arduino, LED-strip, Mini Led Amplifiers and wire?

That should be enough to put you off. Instructables are 99% crap when it comes to electronics.

Hard to say. I don't think they were specifically designed for use with Arduino, and we don't know what's inside them. Just because someone used them in an Instructable does not mean it's a good idea. There are some Instructables that give bad advice that can result in damage Arduinos or shorten their life, for example by overloading individual pins or the atmega chip as a whole. It would help if you could post a link to that Instructable.
Ok, thanks. Could someone post a ebay link of any mosfets that would work for my project?

I'm sure you are capable of doing that yourself. Another suggestion would be IRL540N.
I'd suggest digikey as a source, not ebay.
AOI514, as suggested already:
50 cents each.
Ok, well digikey shipping is 20$ for me so that feels a little steep when I only want components for 1.5$
Would this be ok? Ebay Mosfets
Or is it common for sellers to sell bad quality components on ebay?
Where are you located? Other sources for known good suppliers can be suggested.

Bad quality, counterfeit, fake, etc. are all common on e-bay.
I live in Sweden.
Edit:
Ok I found one supplier in Sweden and the price was 2.5x higher but I will try them anyway.

On Digi-Key UK site they are £0.36, so 3 would be £1.08 plus £12.00 shipping to a UK address! You have to order over £50 to get free shipping.
More questions, the 5050 Led strips power consumption is: 12V/5A/5M.
Would this power supply be enough or should I use a bigger one so there is more margin?
12VDC 5A 60W
12VDC/5A/60W
Would this power supply be enough
Yes.
