Hi guys, I'm having a few issues with this code.
When the button is pressed, the code enters changeLights but the if statement in State1 isn't being met. I've been testing a lot of things but the if statement just won't become true. Not sure why.
Another issue is timing the SSD with State4. I've tried having an if statement when the WritetoSSD is called in order to countdown from 9 to 0 but that seems to not work either.
#define State1 0
#define State2 1
#define State3 2
#define State4 3
#define State5 4
#define State6 5
