LED "pulse" instead of "blink"

AWOL:
But, as you can see, you've introduced a delay into a blink without delay.

You've got me :smiley:
How to do it without it?

On the other hands, thank you for the tip, now both LEDs are working!!!

const int tick = 2;
const int tock = 12;

int tickState = LOW;
int tockState = LOW;
unsigned long previousMillis = 0;

void setup() {
 pinMode(tick, OUTPUT);
 pinMode(tock, OUTPUT);
 Serial.begin(9600);
}
void loop() {
 unsigned long currentMillis = millis();
 int clockspeed = map(analogRead(0), 0, 1024, 1000, 10);
 if (currentMillis - previousMillis >= clockspeed) {
   previousMillis = currentMillis;
   if (tickState = HIGH) {
     tickState = HIGH;
     digitalWrite(tick, tickState);
     delay(7);
     digitalWrite(tick, LOW);
     int comparator = random (0,100);
     int density = map(analogRead(1), 0, 1024, 10, 100);
     if (comparator < density) {
       digitalWrite(tock, HIGH);
       delay(7);
       digitalWrite(tock, LOW);
       } else {
       tockState = LOW;
       }       
   } else {
     tickState = LOW;
   }
   Serial.println(clockspeed);
 } 
}
