Arduino IDE - RGB LED Method

-----------------------------------

 Goal:  Get the RGB light on the Arduino to blink Red, pause for a second, then turn Blue, pause for a second, and turn Green. This should occur just once, so it shouldn't be in a loop, as far as I know

Note: // are line comments, and the specific board I'm using is the Protosnap - Lilypad Development Board (https://www.sparkfun.com/products/11262), Arduino Software Program: https://www.arduino.cc/en/Main/Software, 

What I've Done so Far:

int LED5 = 5;
int LED6 = 6; 
int redPin = 9; 
int greenPin = 11; 
int bluePin = 10; 
int delayTime = 200; // delay is 1/5 of a second

void setup() {

 pinMode(LED5, OUTPUT); // sets the LED 5 to be an output
 pinMode (LED6, OUTPUT); // sets the LED 6 to be an output
 pinMode (A2, OUTPUT); // sets the LED A2 to be an output
 pinMode (A4, OUTPUT); // sets the LED A4 to be an output
 pinMode (A3, OUTPUT); // sets the LED A3 to be an output
 pinMode(redPin, OUTPUT);// sets the redPin (9) to be an output
 pinMode(greenPin, OUTPUT); // sets the greenPin (11) to be an output
 pinMode(bluePin, OUTPUT); // sets the bluePin (10) to be an input
}

void loop(int red, int green, int blue) {

rgbLight(255,0,0); //turn the RGB LED red
 delay(delayTime); //delay
 rgbLight(0,0,0); //turn the RGB LED red
 delay(delayTime); //delay
 rgbLight(0,255,0); //turn the RGB LED green
 delay(delayTime); //delay
 rgbLight(0,0,0); //turn the RGB LED red
 delay(delayTime); //delay
 rgbLight(0,0,255); //turn the RGB LED blue
 delay(delayTime); //delay 
 rgbLight(0,0,0); //turn the RGB LED red
 delay(delayTime); //delay 
 digitalWrite (LED5, HIGH);
 delay (delayTime);
 digitalWrite (LED5, LOW);
 delay (delayTime);
  digitalWrite (LED6, HIGH);
 delay (delayTime);
 digitalWrite (LED6, LOW);
 delay (delayTime);
  digitalWrite (A2, HIGH);
 delay (delayTime);
 digitalWrite (A2, LOW);
 delay (delayTime);
  digitalWrite (A4, HIGH);
 delay (delayTime);
 digitalWrite (A4, LOW);
 delay (delayTime);
  digitalWrite (A3, HIGH);
 delay (delayTime);
 digitalWrite (A3, LOW);
 delay (delayTime);
}

void rgbLight (int red, int green, int blue) {
 analogWrite(redPin, 255-100);
 analogWrite(bluePin, 255-50);
 analogWrite(greenPin, 255-100);
}


I certainly appreciate any help I can get - thanks in advance!  :canada:

Re: Arduino IDE - RGB LED Method

A few things stand out.
The loop() function shouldn't have any arguments.
You pass arguments into rgbLight() but that function ignores them.
Your code is in a loop but you don't want to loop.
Your delay is for 200 ms but you want it to be 1000 ms.
It looks like you're trying to blink the lights in the bottom portion of loop().  Do you mean to do that?

Re: Arduino IDE - RGB LED Method

Ok, I took your suggestions into consideration, here is my new code:

int LED5 = 5; // LED is connected to digital pin 5
int LED6 = 6; // LED is connected to digital pin 6
int redPin = 9; // R petal on RGB LED module connected to digital pin 11
int greenPin = 11; // G petal on RGB LED module connected to digital pin 9
int bluePin = 10; // B petal on RGB LED module connected to digital pin 10
int delayTime = 1000; // delay is a second

void setup(){
 pinMode(LED5, OUTPUT); // sets the LED 5 to be an output
 pinMode (LED6, OUTPUT); // sets the LED 6 to be an output
 pinMode (A2, OUTPUT); // sets the LED A2 to be an output
 pinMode (A4, OUTPUT); // sets the LED A4 to be an output
 pinMode (A3, OUTPUT); // sets the LED A3 to be an output
 pinMode(redPin, OUTPUT);// sets the redPin (9) to be an output
 pinMode(greenPin, OUTPUT); // sets the greenPin (11) to be an output
 pinMode(bluePin, OUTPUT); // sets the bluePin (10) to be an input
}

void loop() { // run forever
rgbLight (0,0,0);
}

void rgbLight (int red, int blue, int green) {
 analogWrite(redPin, 255-red);
 analogWrite(bluePin, 255-blue);
 analogWrite(greenPin, 255-green);
}

void LEDs (){
 rgbLight(255,0,0); //turn the RGB LED red
 delay(delayTime); //delay for 1 second
 rgbLight(0,0,0); //turn the RGB LED red
 delay(delayTime); //delay for 1 second
 rgbLight(0,255,0); //turn the RGB LED green
 delay(delayTime); //delay for 1 second
 rgbLight(0,0,0); //turn the RGB LED red
 delay(delayTime); //delay for 1 second
 rgbLight(0,0,255); //turn the RGB LED blue
 delay(delayTime); //delay for 1 second 
 rgbLight(0,0,0); //turn the RGB LED red
 delay(delayTime); //delay for 1 second 
 digitalWrite (LED5, HIGH);
 delay (delayTime);
 digitalWrite (LED5, LOW);
 delay (delayTime);
  digitalWrite (LED6, HIGH);
 delay (delayTime);
 digitalWrite (LED6, LOW);
 delay (delayTime);
  digitalWrite (A2, HIGH);
 delay (delayTime);
 digitalWrite (A2, LOW);
 delay (delayTime);
  digitalWrite (A4, HIGH);
 delay (delayTime);
 digitalWrite (A4, LOW);
 delay (delayTime);
  digitalWrite (A3, HIGH);
 delay (delayTime);
 digitalWrite (A3, LOW);
 delay (delayTime);
}

I'm not sure exactly sure why the RGB glows white, but I'm guessing it's because all the colours are on at once? How would I fix that so I can show different colours at different times
