One flashing led in while loop and three flashing led's in three for loops.

hi all,

at moment, have red, yellow, green, , blue led's.three running @ 5 flashes each through 3 loops , red colour flashing in each of 3 loops because red typed each of 3 loops. exercise, trying keep 3 different led's running 5 flashes in 3 loops , red led through while loop flash none stop in same sketch. can show me how while loop written keep red led flashing @ times.   

please see working attached sketch.

thank in advance.

code: [select]


int redledpin = 9;
int yellowledpin = 10;
int blueledpin = 11;
int greenledpin = 12;


                       
int redontime = 250;    // red led never goes off in while
int redofftime = 250;   
int yellowontime = 250;
int yellowofftime = 250;
int blueontime = 250;
int blueofftime = 250;
int greenontime = 250;
int greenofftime = 250;

int numredblink = 5;
int numyellowblink = 5;
int numblueblink = 5;
int numgreenblink = 5;

void setup() {
  serial.begin(115200);
  pinmode(redledpin, output); 
  pinmode(yellowledpin, output);
  pinmode(blueledpin, output);
  pinmode(greenledpin, output);
}

void loop() {

  (int j = 1; j <= numyellowblink; j = j + 1) {
    digitalwrite(yellowledpin, high);
    digitalwrite(redledpin , high);
    delay(yellowontime);
    digitalwrite(yellowledpin, low);
    digitalwrite(redledpin, low);
    delay(yellowofftime);
  }
  (int k = 1; k <= numgreenblink; k = k + 1) {
    digitalwrite(greenledpin, high);
    digitalwrite(redledpin, high);
    delay(greenontime);
    digitalwrite(greenledpin, low);
    digitalwrite(redledpin, low);
    delay(greenofftime);
  }
  (int k = 1; k <= numblueblink; k = k + 1) {
    digitalwrite(redledpin, high);
    digitalwrite(blueledpin, high);
    delay(blueontime);
    digitalwrite(redledpin, low);
    digitalwrite(blueledpin, low);
    delay(blueofftime);
  }
  }




throw away loops , while loops , figure out how let loop function looping , done if statements.  no loops , no delay.  when there can anything.  you're wasting time learning write blocking code in loops.  make things harder on later when have unlearn that.
