Sorry to be a pain guys
But how would I go about
Pressing a push button
That starts 5 leds for seperate blink durations
Then all to finish after there associated time on
Looking for help with coding I don’t even know where to start
So set yourself a simpler challenge unless this is an assignment.
Is it?
Start with blink without delay and/or beginner's using millis(). and this page to show how to wire a momentary switch (button),
Get one LED to turn on with the button switch and off after a time.
Get 2 or 3 to turn on by the switch and off after separate times.
Then, maybe, study arrays to reduce the amount of code required and make it easy to add LEDs without writing a bunch of new code.
