Arduino interupt a delay function

in my next project i use 4 Leds with delay(10000). I need a function for cancel this loop and start again with a new delay value e.g. 100.

I have enabled interrupts and when i pressed a button, delay changed to 100 AFTER a round. I have to wait 10 seconds.. It is possible to restart the loop function with the new values?

Wow that was rude ignacio At least be helpful.

You can do this but not as you have implemented.

Delay is not good to be used in this circumstance. A much better way of implementing is to use a while loop like this:

int delayLED = 10000;

int beginMillis = millis();

while( millis() - beginMillis < delayLED)
{
    // insert the code for your "interrupt" here
    // kinda like this
    if(button pressed)
    {
        delayLED = 100;
        break;
    }
}

This is just a template not a complete answer. Let me know if you have further questions.

Happy coding!
