I set button for 2 functions. But its only turn on leds. Can someone say how to code led’s to blink?

#2

Look at the BlinkWithoutDelay example sketch.

#3

I tryd to insert the code. But led just staying on...

#4

Maybe a bit of a boring answer, but as there this code has many ifs, elses and elseifs: Have you tried using serial.println to figure out what blocks are being ran and which arent?

My guiss is that if you know the order things are run in, you’ll know if it behaves as you intended when programming. If conditions you assume to be true, actually are true, etc.

Then show us that code, otherwise we have to guess what you did.

this is my first project with arduino, so please be patient :))
