Hello everyone.
Before writing, I clarify that I do not buy any kit, I assembled it on my own, buying the resistances and mounting it on a protoboard.
Everything works perfect, except that gradients look weird.
The pure colors look perfect, when combining colors it looks like saturated, I attach images so that you understand what I'm talking about: https://imgur.com/a/pUodiQb.
I am using resistances of 5% tolerance, and I read in the manual that the 500 Ohms should be as close as possible, in this case I am using 470 Ohms, this interferes? Somebody could help me? I would appreciate it very much, greetings!
