4 leds and a button

[J-M-L]

@john_hawkins

I'm really tired and stupid)?

Tired possibly - stupid I would not say so as your attempt is a constructive step forward.

When you look at

@john_hawkins

if(g==0){
      digitalWrite(pin[0],HIGH);
      if(ct-pt>=dt){
      pt=ct;
      digitalWrite(pin[0],LOW);
      }
      digitalWrite(pin[1],HIGH);
…

I see requests to turn on leds that are independent of the timing comparison, so this will happen every time you cycle through the loop/if

Is that intended?

The logic could be

• record start time upon initial button press (state change detection). Do that only once if the button stays pressed
• if button is still pressed, use current time comparison with that start time to decide which leds should be on or off
• if button is released, turn everything off
• rinse and repeat
