inverse signal by timer millis

i need a two single also needs a shift for the second signal

1. int ledPin1 =  12;  // the number of the LED pin
2. int ledState1 = LOW;  // ledState used to set the LED
3. unsignedlong previousMillis1 = 0;  // will store last time LED was updated
4. longOnTime1 = 250;  // milliseconds of on-time
5. longOffTime1 = 750;  // milliseconds of off-time
6. int ledPin2 =  13;  // the number of the LED pin
7. int ledState2 = LOW;  // ledState used to set the LED
8. unsignedlong previousMillis2 = 0;  // will store last time LED was updated
9. longOnTime2 = 330;  // milliseconds of on-time
10. longOffTime2 = 400;  // milliseconds of off-time
11. void setup()
12. {
13. // set the digital pin as output:
14.   pinMode(ledPin1, OUTPUT); 
15.   pinMode(ledPin2, OUTPUT); 
16. }
17. void loop()
18. {
19. // check to see if it's time to change the state of the LED
20. unsignedlong currentMillis = millis();
21. if((ledState1 == HIGH) && (currentMillis - previousMillis1 >= OnTime1))
22.   {
23.   ledState1 = LOW;  // Turn it off
24.   previousMillis1 = currentMillis;  // Remember the time
25.   digitalWrite(ledPin1, ledState1);  // Update the actual LED
26.   }
27. elseif ((ledState1 == LOW) && (currentMillis - previousMillis1 >= OffTime1))
28.   {
29.   ledState1 = HIGH;  // turn it on
30.   previousMillis1 = currentMillis;  // Remember the time
31.   digitalWrite(ledPin1, ledState1);  // Update the actual LED
32.   }
33. if((ledState2 == HIGH) && (currentMillis - previousMillis2 >= OnTime2))
34.   {
35.   ledState2 = LOW;  // Turn it off
36.   previousMillis2 = currentMillis;  // Remember the time
37.   digitalWrite(ledPin2, ledState2);  // Update the actual LED
38.   }
39. elseif ((ledState2 == LOW) && (currentMillis - previousMillis2 >= OffTime2))
40.   {
41.   ledState2 = HIGH;  // turn it on
42.   previousMillis2 = currentMillis;  // Remember the time
43.   digitalWrite(ledPin2, ledState2);  // Update the actual LED
44.   }
45. }

thank you my code))

I wanted a signal to be executed on a single press. but if pressing the button falls into the timing, then the signal is triggered accordingly if you wait a long time and press the button nothing happens))) how can I fix unsigned long previousMillis = 0;

thanks a lot for the code

#define load_button 9

const int ledPin =  11;

const int ledPin2 =  12;

// Variables will change:

int ledState = LOW;             // ledState used to set the LED

int ledState2 = LOW;

// Generally, you should use "unsigned long" for variables that hold time

// The value will quickly become too large for an int to store

       // will store last time LED was updated

unsigned long previousMillis = 0;

void setup() {

  // set the digital pin as output:

  pinMode(ledPin, OUTPUT);

  pinMode(ledPin2, OUTPUT);

  pinMode(load_button, INPUT_PULLUP);

}

void signal(){

  unsigned long currentMillis = millis();

  if (currentMillis - previousMillis >= 0 && currentMillis - previousMillis <= 1000) {

    digitalWrite(ledPin,HIGH);

     }

  else{

    digitalWrite(ledPin,LOW);

    }

  if (currentMillis - previousMillis >= 400 && currentMillis - previousMillis <= 5000) {

    digitalWrite(ledPin2,HIGH);

     }

  else{

    digitalWrite(ledPin2,LOW);

    } 

}

void loop() {

if (digitalRead(load_button) == LOW) {

    signal();

  }

}

sorry i cant correctly input this code

its a repeat cycle of pwm i need a single

You need to set previousMillis to currentMillis at the end of signal() otherwise it is always zero and after 5 seconds neither of your ‘if’ checks will return true.
