Problem with functions in my project

Projects Programming

Hi guys, i´m here in hope to know what´s happening , my project it´s a traffic light and I can´t understand why the functions doesn´t work here is it:

//Atribuindo à uma variavel um numero de pino.
   int verde = 8;
    int amarelo = 7;
     int vermelho = 6;

   
   
void setup() {
  
  //Definição dos pinos ENTRADA/SAIDA de dados.
  pinMode(verde, OUTPUT);
   pinMode(amarelo, OUTPUT);
    pinMode(vermelho, OUTPUT);


}

void loop() {
 

  int ciclonormal();
}


int ciclonormal() { //Define a função do ciclo nromal

     
     digitalWrite(vermelho, HIGH);
      delay(1000);
       digitalWrite(vermelho,LOW);
        delay(50);
         digitalWrite(verde, HIGH);
          delay(1000);
      digitalWrite(verde, LOW);
       delay(50);
        digitalWrite(amarelo, HIGH);
         delay(500);
          digitalWrite(amarelo, LOW);
           delay(50);
        }

What do you want achieve with the posted sketch?

Hello
Welcome to the Arduino fora.
Before you do anything else please take a moment to read General guidance
And How to use this forum
Especially item #7 on posting code (code tags good, complete mess bad).
What does 'doesn't work' mean? What should it do? What does it do instead?

You also need to get away from using delay(), have a read of:
Using millis for timing
Demonstration for several things at the same time

void loop()
{
  int ciclonormal();
}

That is not a function call, it is a function definition.

This is a function call

void loop()
{
  ciclonormal();
}

UKHeliBob:

void loop()

{
  int ciclonormal();
}

Thank you friend! I´m new in Arduino programming, you helped me so much!

Is the following a function call?

int x = ciclonormal();

Is the following a function call?

Yes. It calls the function and as long as the function is not declared void and returns an int it will be assigned to the x variable that has just been declared

Cool!
