Hi, I've got a timer function that decreases the time on the LCD each time it's called, then I'm calling a function that does the "Knight Rider" sort of effect on the neopixel 8x, it takes exactly 1 second till the led moves to right and one second till it comes to left. It works fine and all but it's using the delay function that pauses everything else and I need to do some other things in the main loop too, so I looked for a way to "multithread" the functions but I found out that multithreading is impossible on the arduino uno and i can only do protothreading, for which i can't really use the for loop. So i splitted the whole for loop into multiple if statements and followed the "Blink without Delay" example. However the delay is not constant, it moves 2x slower and sometimes it moves faster and so on. I'm not really sure where i made the mistake.
