Damn it, they really ripped off then. The best thing would be, like you said, to order the components off of adafruit but being from Spain and needing them as fast as possible to be able to hand in the project on time, it would´ve been risky if it gets stopped on customs (same goes for aliexpress and banggod and so on). So my only option was amazon and I did what I could honestly, even though it might not be the best solution.
I´ll try using that library and with some luck it´ll all work out just fine before my due date (aka in about 2 weeks for the whole lamp lol)
Appreciate all this advice too, if I make another cool arduino project on my own free time I´ll be sure to get the things from proper sellers.
Thanks man!!
