3 led go high and off with interrupt and millis, would be nice with more veriabe

I would like to make this code work

3

What do you want to vary ?

Apart from experimenting with functionality there is no need to use interrupts to do what are doing

4

Yes, that's correct but i would like to make this work with them if it's possible. I would also like to make the mills command work. There is something wrong with my code concerning mills function.

5

Please explain in words what you would like the program to do and what it does now

6

what the program does now : each time pressed on "button" it changes from led also changing led brightness.

What i want it to do : If pressed on button i would like it to roam between these 3 leds changing brightness between leds and then stopping when i press on "button" again.

7

Should the change of brightness be linear or random and what will determine the upper and lower limits and the time between changes of brightness ?
