Hello everyone ! Sorry for my english....
I built a cool "coin pusher machine" for my best friend's birthday. It took me a long time but everyt mechanic parts are ok and working.
Well.... I do have a problem with arduino. I'm not really good at it and i don't have time anymore to learn more...
I used Wokwi, arduino forums, examples, libraires, generators, etc to try to create a code. It does work on simulator (more or less!) but i'm stuck...
Here's the main problem : when button is hit, scrolling text stops. What i would like is this 
- When button is pressed : Replace the scrolling text by "BONUS" + a cool light effect on the neopixelring. Few seconds after, servo motor moves.
Then back to normal !
I guess it's something with non blocking code ?!
Here's the main problem but i do haveother ones to check after (not so responsive button + add sound when bonus is activated, etc....) Well, one step at a time i guess...
THANK YOU SO MUCH. Really !`
