Noob here, help needed
Hi all, i m student and i do this for the school project for the first time.
I have idea how it should look but i cant anywhere find will it work.
If anyone can tell is this right or not and if not where i make mistake?
Nope, will not work. Did you try Google 
I hope the answer is no or you should do a (refresh) course on finding information aka Googling.
You need to drive each of the R, G & B lines with a transistor (MOSFET preferred). If you don't know how this is done, and Google fails you, feel free to ask ;D
And include things like, how many RBG LEDs will be on your strip and if possible, what the max current specification is, etc. If you don't have that information, then we can either assume 20mA/LED color/chip, or maybe there are numbers on the side of one of the LED chips that are meaningful, or you can sacrifice a section to testing (which is always fun :D).
