Arduino - how to use structures?

Question

Arduino

I've been struggling with structures all morning, a
simple sketch I took from the website
playground.arduino.cc/Code/Struct
compile error

struct RGB {
  byte r;
  byte g;
  byte b;
};

RGB variable = { 255 , 0 , 0 };

variable.r = 0; // здесь падает ошибка - test:10: error: 'variable' does not name a type

void setup() {}
void loop() {}

I also tried a dozen more struct / typedef options - they all end up with a similar assignment error.

Answer 1

Put variable.r = 0;in a function.
