hello world!
setup:
3 switches
3 lights
3 sounds
each switch should turn on one light and play one sound. but only one at a time and while one is running, it shouldn't listen to the others. how can i stop or block the pins from reading while another function is running?
problem in my sketch is, that while one is on and i press another switch(or the same switch again), it notes all the presses and performs them after the running one is finished.
i already spent 2 days trying with while, if, else if, switch case, return, break.. but still no success. the result was either, that it doesn't play to the end or it played the other stuff right behind. it shouldn't.
it seems to me, that i don't understand the basic flow of loops?!
i simplified the sketch for you and left out one light and all the audio stuff. the "returns" might be stupid as well, because didn't make any difference as i remember. the Serial.prints are just for checking
i'm losing my faith..
