Timings of differen

Using Arduino LEDs and Multiplexing
1

Hi, I’m trying to do the following:
Press push button once
White LED flashes 4 times
After the last flash 3 LEDs (green, red, and yellow) run through a fade sequence together for about 10 seconds
Then everything off until button is pressed again.
Currently when my nano is powered the green, red and yellow LED start fading straight away, when the button is pressed they go static on and the white LED flashes then the fade starts again for ever. I’ve tried adding ‘if button high’ with a delay before the fade section but didn’t work and I also added
‘analogWrite(xx LOW)’ in setup and loop section. Neither worked.
My code is as follows. Any help would be greatly appreciated.

//resemble starting fire with flint
//white led flashing to show flint and steel followed by fire effect LED

const int bb = 2;
  // push button connected to pin 2 with 10k pull down resistor
const int wled = 9;
  // white LED connected to pin 9 270ohm resistor

int rled = 5;
  // LED red connected to pin 5 270ohm resistor
int yled = 6;
  // LED yellow connected to pin 6 270ohm resistor
int gled = 3;
  // LED green connected to pin 3 270ohm resistor
int bbs = 0;  // push button state 

void setup() {
  // nothing happens in setup
  pinMode(wled, OUTPUT);
  pinMode(bb, INPUT);
}

void loop() {
  bbs = digitalRead(bb);

  if (bbs == HIGH) {
    digitalWrite(wled, HIGH);
    delay(100);
    digitalWrite(wled, LOW);
    delay(1000);
    digitalWrite(wled, HIGH);
    delay(100);
    digitalWrite(wled, LOW);
    delay(1000);
    digitalWrite(wled, HIGH);
    delay(100);
    digitalWrite(wled, LOW);
    delay(1000);
    digitalWrite(wled, HIGH);
    delay(100);
    digitalWrite(wled, LOW);
    delay(1000);
  }
  // fade in from min to max in increments of 5 points:
  for (int fadeValue = 155; fadeValue <= 255; fadeValue += 50) {
    // sets the value (range from 0 to 255):
    analogWrite(rled, fadeValue);
    // wait for 30 milliseconds to see the dimming effect
    delay(30);
  }
  for (int fadeValue = 0; fadeValue <= 100; fadeValue += 50) {
    // sets the value (range from 0 to 255):
    analogWrite(yled, fadeValue);
    // wait for 30 milliseconds to see the dimming effect
    delay(10);
  }
  for (int fadeValue = 0; fadeValue <= 6; fadeValue += 5) {
    // sets the value (range from 0 to 255):
    analogWrite(gled, fadeValue);
    // wait for 30 milliseconds to see the dimming effect
    delay(10);
  }

  // fade out from max to min in increments of 5 points:
  for (int fadeValue = 255; fadeValue >= 200; fadeValue -= 50) {
    // sets the value (range from 0 to 255):
    analogWrite(rled, fadeValue);`Use code tags to format code for the forum`
    // wait for 30 milliseconds to see the dimming effect
    delay(100);
  }
  for (int fadeValue = 160; fadeValue >= 0; fadeValue -= 50) {
    // sets the value (range from 0 to 255):
    analogWrite(yled, fadeValue);
    // wait for 30 milliseconds to see the dimming effect
    delay(30);
  }
  for (int fadeValue = 6; fadeValue >= 0; fadeValue -= 5) {
    // sets the value (range from 0 to 255):
    analogWrite(gled, fadeValue);
    // wait for 30 milliseconds to see the dimming effect
    delay(100);
  }
}

Look in the documentation at Arduino.cc to learn what the return values are for digital read.

You need to configure these y, r and g as OUTPUT.

Not true.

Also not true. Either correct your comments, or remove them

When you move the close brace that was at the end of the blinking white LED, and move the brace to the end of the sketch, it "works." Note that an LED that "fades' from 155 to 255 in 50 bit increments will not be noticed as a fade. Same goes with a "fade" from 0 to 6 by 5 bit steps. Read your sketch again. You should "fade from 25 to 255 by 5 for best fade effect.
