HI guys, I'm new at arduino, so i want to make 2 LED to On and off but different delay LED 1 digitalWrite(LED_1,HIGH); delay(2000); digitalWrite(LED_1,HIGH); delay(500); and LED 2 digitalWrite(LED_2,HIGH); delay(500); digitalWrite(LED_2,HIGH); delay(2000); how to combine these 2 different line…

ok, start with looking at the blink without delay example in the IDE. You have fallen into the standard beginners trap in Arduino of using 'delay'. This is sometimes used in tutorials because it is simple but it is not useful for any significant code. Delay means to stop for a period of time, it …

const byte LED1 = 3, LED2 = 7 ; boolean LEDstate = false; void setup () { pinMode ( LED1, OUTPUT ); pinMode ( LED2, OUTPUT ); } void loop () { LEDstate = ( millis () / 500 ) % 5; digitalWrite ( LED1, LEDstate ); digitalWrite ( LED2, !LEDstate ); } [image] sketch.ino - Wokwi Ar…

[image] casperudin: how to combine these 2 different line code in one program?? Since all you ever do is turn on both LEDs, this modification of @flashko 's code should work: const byte LED1 = 3, LED2 = 7 ; void setup () { pinMode ( LED1, OUTPUT ); pinMode ( LED2, OUTPUT ); digitalWri…

void loop() { unsigned long time = millis(); digitalWrite(LED_1,(time%2500)<2000); digitalWrite(LED_2,(time%2500)<500); } So how does this work? The variable time % 2500 returns a value between 0 and 2500 or the remainder when divided by 2500 With only the remainder from the division remain…

[image] casperudin: LED 1 digitalWrite(LED_1,HIGH); delay(2000); digitalWrite(LED_1,HIGH); delay(500); and LED 2 digitalWrite(LED_2,HIGH); delay(500); digitalWrite(LED_2,HIGH); delay(2000); Did you mean to turn the LEDs ON and OFF: // LED_1: On for 2000, off for 500 digitalWrite(LED_1,HI…
