Too few arguments to function problem

Projects Programming
1

I have some problem with my code, it keeps saying "too few arguments to function 'void digitalWrite(uint8_t, uint8_t)'" do you guys have any idea why this isn't working?

int verde=10;
int amarillo=11;
int rojo=12;
int sensor=13;
int lyd=9;


void setup() { 
pinMode(sensor,INPUT);
pinMode(verde,OUTPUT);
pinMode(amarillo,OUTPUT);
pinMode(rojo,OUTPUT); 
pinMode(lyd,OUTPUT);
} 




  void loop() {

  digitalWrite(rojo, HIGH);

  if (digitalRead(sensor)==HIGH) 
  {
    digitalWrite(rojo, LOW);
    digitalWrite(amarillo,HIGH);
    delay(3000); //wait 3 seconds; 
    digitalWrite(amarillo,LOW);
    delay(250); //wait 0.25 seconds;


    digitalWrite(verde,HIGH); 
    delay(15000); //wait 15 seconds; 
    digitalWrite(verde,LOW); 
    delay(250); //wait 0.25 seconds;



    digitalWrite(amarillo,HIGH);
    delay(3000); //wait 3 seconds;
    digitalWrite(amarillo,LOW);
    delay(250); //wait 0.25 seconds;


    digitalWrite(rojo,HIGH); 
    delay(15000); //wait 15 seconds; 
    digitalWrite(rojo,LOW); 
  }

  else  
  {
  digitalWrite(rojo, HIGH);    
  delay(10); 
  }
 
          if (digitalWrite(verde)==HIGH)
          {

        digitalWrite(lyd, HIGH);
        delay(500); // Wait for 500 millisecond(s)
        digitalWrite(lyd, LOW);
        delay(500); // Wait for 500 millisecond(s)
        digitalWrite(lyd, HIGH);
        delay(500); // Wait for 500 millisecond(s)
        digitalWrite(lyd, LOW);
        delay(500); // Wait for 500 millisecond(s)
        digitalWrite(lyd, HIGH);
        delay(500); // Wait for 500 millisecond(s)
        digitalWrite(lyd, LOW);
        delay(500); // Wait for 500 millisecond(s)
        }

        else 
        {
        digitalWrite(lyd, HIGH);
        delay(1500); // Wait for 1500 millisecond(s)
        digitalWrite(lyd, LOW);
        delay(1500); // Wait for 1500 millisecond(s)
    
        }
  }

Here it is:

  if (digitalWrite(verde) == HIGH)
3 
          if (digitalWrite(verde)==HIGH)

Did you mean to use digitalRead() ?

Hello markuskjelstrup, your post has been moved to the Programming section where it fits better.
