too few arguments to function error[SOLVED]

Projects Programming

I am having an issue with my code. The ide keeps saying: too few arguments to function 'void digitalWrite(uint8_t, uint8_t)'.

My code is:

int red = 3;
int yellow = 5;
int green = 8;

int blue = 13;

int activate = 7;

void setup() {
  // put your setup code here, to run once:
  pinMode(activate, INPUT_PULLUP);
  pinMode(red, OUTPUT);
  pinMode(yellow, OUTPUT);
  pinMode(blue, OUTPUT);
  pinMode(green, OUTPUT);
 }

void loop() {
  // put your main code here, to run repeatedly:
  if (digitalRead(activate) == HIGH)
  {
    digitalWrite(green) == LOW);
    digitalWrite(yellow) == HIGH);
    delay(3000);
    digitalWrite(yellow) == LOW);
    digitalWrite(red) == HIGH);
  }
  else if (digitalRead(activate) == LOW)
  { 
   digitalWrite(green) == HIGH);
   digitalWrite(blue) == LOW);
   digitalWrite(red) == LOW);
   digitalWrite(yellow) == LOW);
  }
}

I am using the UNO board

I am using 5 led's(one red, one yellow, one green, two blue), five 220ohm resistors(one per LED), and one button.

Pin setup:
the two blue led's to pin 13
red led to pin 3
yellow led topin 5
green led to pin 8
button(activate in code) to pin 7

Did i code it wrong? Does anybody know the solution? I tried the else if as an if function already.

(For fun, I atached the blue led's to pin D13 to see the board led blink [Uno prototype shield atached.])

Go to the C++ reference section to see if you are doing this correctly:

digitalWrite(green) == LOW);

Look at the syntax of the function: Syntax

digitalWrite(pin, value).

Does that look like what you have?

Thanks larryd, i didn't catch that.

i tried that, but it did not work. here is my work:

int green = 9;
int yellow = 10;
int red =11;
int motor = 3;

void setup() {
pinMode(green, OUTPUT);
pinMode(yellow, OUTPUT);
pinMode(red, OUTPUT);
pinMode(motor, OUTPUT);
}

void loop() {
pinMode(green) == LOW);
pinMode(yellow) == LOW);
pinMode(red) == LOW);
pinMode(motor) == LOW);
pinMode(green) == HIGH);
delay(500);
pinMode(yellow) == HIGH);
pinMode(red) == HIGH);
pinMode(motor) == HIGH);
}
