I'm trying to make this simple game similar to a Simon game but different. The code feels like it's close but I'm getting a wrong answer time every time I try to play it.
I want the Arduino to light up 4 or 5 leds and the player pushes buttons that correspond to those leds in the same order to advance to the next level. As they get them correct a neopixel illuminates another pixel. It's just a simple kids game but I don't get to dabble with the IDE much so I'm always struggling a bit.
This code starts when the start button is pushed, runs through the leds then when I hit a button it always says error even though it's not.
I've ran some different code on the setup and it all works from a hardware side. Anyone see anything super obvious wrong in this code? THANKS!
